A major portion of building the Muslim personality comes from the Islamic fundamental source, al Tazkiyah or the purification of the heart and soul. Through tazkiyah comes spiritual health and morality. The traits of loving of Allah and His Prophets, adorning and practicing the ninety-nine attributes of Allah, applying the virtues of compassion and mercy, holding one's brother or sister's well-being higher than one’s own self, generosity, piousness, trustworthiness and much more are consequent virtues of tazkiyah.

The Place of al Tazkiyah in the Sight of Allah
Let us go over the following verses of Surah Abasa or Frowned and review their story to better understand the place of tazkiyah to Allah (SWT). Allah said:

"(The Prophet) frowned and turned away, because there came to him the blind man [interrupting]. But what could tell you [Oh Muhammad] that perchance he might grow in spiritual understanding, yazzakka? - or that he might receive [mental] admonition, and that the teaching might benefit him? As for he who thinks for himself as self sufficient [in reference to a member of Quraysh whom the Prophet had hoped to bring to Islam], to him you give attention and not upon you [is any blame] if he does not grow in spiritual understanding, yazzakka."

The story in the above verses is that Prophet Muhammad (p) was speaking to an influential member of Quraysh whom the Prophet had hoped to enlighten with Islam. During this time, a companion of the Prophet who was blind (Abdallah ibn Umm Maktum) approached the Prophet interrupting him seeking tazkiyah, spiritual gain and guidance. The Prophet frowned and turned his face away from Abdallah. In response to the Prophet’s action, Allah revealed the Chapter of Abasa instructing the Prophet not to be distracted from anyone seeking tazkiyah.
Aside from the lesson learned to withhold no spiritual admonition from anyone seeking it, what is in this story for us is to discover the unique and prestigious position that Allah placed upon tazkiyah.

Tazkiyah is one of the spiritual goals of the Islamic faith. This fact is uncovered as Allah taught His Prophet 'the no frowning lesson.' In the first instance, for example, Allah addresses Prophet Muhammad: “But what could tell you [Oh Muhammad] that perchance he [the blind man] might grow in spiritual understanding (yazzakka).” This questioning of the Prophet over his delivery of "tazkiyah" to the blind man is a clear evidence showing that "tazkiyah" is a matter with a crucial place and value to Allah (SWT).
In the second instance, in a similar manner to the first instance, Allah questiones the Prophet’s delivery of tazkiyah persistently to the arrogant person. “As for he who thinks for himself as self sufficient, to him you give attention and not upon you [is any blame] if he did not grow in spiritual understanding, yazzakka .”

In those two instances, the burdensome demand of Allah is centered on tazkiyah and the manner in which the Prophet is delivering it. Thus, there is an undeniable indication of the magnitude and significance of tazkiyah is to Allah and therefore in the Islamic faith and Muslim's daily living.

If tazkiyah is so central and dear to Allah, a believer must certainly act Inelegantly to attain it by seeking closeness to Allah in conducting thikr, night prayers, reading, understanding and applying the words of the Qur’an. Those who wanted to be loved by Allah and attain the success in this world and in the Hereafter must grow and never cease to observe and practice tazkiyah. This fact becomes very plain as Allah makes His claim over tazkiyah in the following verses:

"Truly he succeeds who (zakkaha) purifies it (i.e., nafs, the soul or inner-self). And he fails who corrupts it."

Preceding these two important verses, Allah swore seven times emphasizing the culminating promise that it is tazkiyah that plays a significant role in the success of the believer. Here is the English translation of Verses 1 through 10 of Surah al Shams (91).

"By the Sun and his (glorious) splendour; By the Moon as she follows him; By the day as it reveals (the Sun's) glory; By the Night as it conceals it; By the Firmament and its (wonderful) structure; By the Earth and its (wide) expanse; By the Nafs (Soul), and the proportion and order given to it and its enlightenment as to its wrong and its right: - truly he succeeds who purifies it, and he fails who corrupts it!"

Ibn Abbas narrated that when the Messenger of Allah read this verse (Truly he succeeds who purifies it, and he fails who corrupts it!), he used to stop reciting and say:

O Allah, give to my inner-self (nafsi) piety (taqwa), for You are its Guardian and its Master, and the best Purifier."

Also Ahmad in his Masnad (Source of Prophetic Traditions) reported that 'A'isha, the Prophet's wife, said that one night she did not find the Prophet (p) in his bed. With her hands, groping in the dark, she found the Prophet (p) in prayer, prostrating and saying:

"O my Lord, grant my inner-soul piety and purify it, for You are the best Purifier, You are its Guardian and its Master."

The messengers of Allah, the learned men and women who are rich in spirituality, piety and guidance, are the teachers who help people attain tazkiyah.

The Remembrance of Allah, Thikru Allah
One of the most important constituents of tazkiyah is thikru Allah (remembrance of Allah). Thikru Allah or simply thikr is a term used to reflect a collection of ways in which a Muslim remembers, lives, and attains closeness to Allah in his heart and himself. The word remember alone does not reflect the meaning of the word thikr. Thus, thikr is more than recollection of something in memory. Thikr is a training institution that helps develop people with enlightened hearts, totally occupied with Allah and His attributes. Allah has told us:

"Say (O Muhammad): Truly, Allah leaves to stray whom He will (as a result of their choice of going astray), but He guides to Himself those who turn to Him in penitence, those who believe, and whose hearts find satisfaction in the remembrance of Allah, for without doubt in the remembrance of Allah do hearts find rest." Qur’an, 13:27-28.

Furthermore, the Prophet (p) is reported to have said:

"The faith of a servant (worshipper) will not be right, complete and straight (yastaqeem), unless his heart is straightened (yastaqeem, i.e. wholly engaged in loving Allah, lovingly obedient to Allah, and totally hateful of disobeying Him)."

Shaddad ibn Aws reported that in the salah (prayer) the Prophet (p) used to ask Allah for a heart in awe of Him, free from the distress and agitation of sin, saying:

"I ask You, (O Allah) for a good heart."

The ninety-nine noble attributes of Allah are heaven of spiritual enrichments. Each noble attribute is an institution that speaks about Allah. A true believer loves Allah more than anything else. Therefore, these noble attributes will allow a person to be trustworthy, honorable, wise, beneficent, successful, humble, and in awe of Allah. As a result of this knowledge and close attendance to Allah, righteous acts become natural in a person, and evil acts become infrequent. This result naturally comes from the reflections and deep knowledge of Allah and His attributes.

A Muslim can accomplish a change in his heart through the mechanism of thikr. Allah offers a variety of means to achieve piety, tranquility, humility, and reverence. One way to begin making thikr is to start out by attaching your heart to Allah and by linking it to His guidance. The Prophet (p) said:

"Truly in the body there is a morsel of flesh, and, if it is guided (to the way of Allah), the whole body will be guided and follow accordingly, and if this organ is left to go astray, the whole body will follow and go astray; truly this (organ) is the heart."

When the heart is cleansed from all vices and enlightened by the guidance of Allah, the rest of the body and all the senses will follow accordingly. Furthermore, the Prophet (p) pointed out the important role of faith in the heart, when he said:

"Verily, faith in your hearts wears out, just as clothes do. So ask Allah to renew faith in your hearts."

Abu Dawood, al Nissa'i, and Ibn Majah in their Masanid (Records of Prophetic Traditions), respectively reported that Abu Sa'eed al Khidri quoted the Prophet (p) as saying:

"If a man, during the night, wakes up his wife, and then they conduct two rak'ah, (a prayer unit), they are considered (in terms of rewards and honor) for that night amongst the people of thikr, 'al thakereen and al thakirat'."

Thikr utilizes the signs of Allah and His creations as means of recollection and contemplation. The attributes: the Merciful, the Wise, the Pure, the Able, the King, the Cherisher, the Gracious, the Exalted, the Dominion, and the Master are a few of the attributes from which the spiritual nourishments of a pious believer are drawn.

There are many more signs the Qur'an often alludes to which a believer contemplates. The universe, for example is one of them. Modern science tells us that it is over one hundred and fifty billion light years wide. This vast universe holds over one hundred billion galaxies, each with billions of stars and planets. There is an eternal creation and destruction of new stars and planets. This could illustrate the Judgment Day and the end of our planet.

In addition, signs such as the creation of people, animals, the world, and the physical and intellectual relationships existing within all this creation are indicators and signs of His Majesty, Wisdom, and Greatness. Allah's signs are present everywhere: His beautiful attributes are witnessed and abide in each tiny atom of matter; they abide throughout the entire immeasurable universe. Contemplating the universe can also remind us of some other signs of Allah, such as Heaven and Hell, and the Hereafter.

There are over seventy-five verses in the Holy Qur'an that speak about thikr separately by name. These verses speak of and reflect on this subject in a variety of ways. Moreover, there are hundreds of other places where thikr is mentioned by implication through glorification and reflection. Here are some examples:

"Do they not travel through the land, so that their hearts may thus understand (and learn wisdom), and their ears may thus hear? Truly it is not their eyes that are blind, but their hearts which are in their breasts." Qur’an, 22:46.

"On earth are signs for those of assured faith, as also in your own selves. Will you not then see?" Qur’an, 51:20 and 21.

"Is it not a warning to such people (to call to mind) how many generations before them We destroyed in those haunts where they (now) move? Verily, in this are signs for people endued with understanding." Qur’an, 20:128.

"If We sent down this Qur'an on a mountain, verily, you would have seen it humble itself and cleave asunder in awe of Allah. Such are the analogies that We propound to people, so that they may reflect." Qur’an, 59:21.

"So when you have accomplished your holy rites, celebrate the praise of Allah, as you used to celebrate the praises of your fathers, yea, with far more heart and soul." Qur’an, 2:200.

(O reader!), bring your Lord to remembrance in your (very) soul, with humility and in reverence, without loudness in words, in the mornings and evenings; and be not yourself of those who are unheedful." Qur’an, 7:202.

What a heartsoothing and culminating verse is the last. I think every Muslim should, on a daily basis, make a silent, personal, hearty, self-accountable meeting with Allah, morning and evening, to share the concern of Allah that this verse speaks of. Muslims should make this verse a daily practiced sunnah.

One must understand that thikru Allah is not just moving the lips and the tongue with the praises of Allah, but with an absent mind and heart. Thikru Allah is that beautiful feeling and deep satisfaction produced when a person conducts thikr with complete concentration of one's heart and mind.

"But keep in remembrance the name of your Lord and devote yourself to Him wholeheartedly." Qur’an, 7:8.

"Oh you who believe! Let not your riches or your children divert you from the remembrance of Allah. If any do so, the loss is their own." Qur’an, 63:9.

There are many more forms of thikr: prayers during the night, supplication, meditation, and contemplation, as well as reading and studying the Holy Qur'an and the Traditions of the Prophet (p). Thikr increases faith, enlightens our inner-selves, brings people closer to Allah, and yields tranquility and joy in the heart. Self satisfaction and comfort can be actualized only when a person maintains Allah in his or her heart and pleases Him. Allah reveals:

"Undoubtedly, believers are those who, when Allah is mentioned, their hearts tremble, and, when they hear His verses rehearsed, find their faith strengthened, and put (all) their trust in their Lord." Qur’an, 8:2.

This kind of deep faith in Allah will result in less inclination to use the world simply to collect money and achieve power. Thikru Allah is a primary ingredient in making a true believer who epitomizes all moral virtues (husnu al khuluq). Triumph and prosperity in life are directly related to the degree of practice of the virtues of this school of spiritual guidance, tazkiyah. Almighty Allah said:

"But the ultimate success (falah or prosperity in the highest sense) is for the one who purifies oneself (in spiritual guidance) and remembers (glorifies and meditates on) the name of one's Guardian Lord (to enhance one's spirituality),and then performs the prayer (salah)." Qur’an, 87:14-15.

Trust is certainly a minimum requirement for having a successful business. Tazkiyah, however, is the foundation not only of trust, but also of goodness and of honest relations. Thikru Allah is the cornerstone for loving Allah and practicing the virtues and traits of His attributes. Thikru Allah clears away all corruption and mischief, and this is truly the gateway to prosperity. Furthermore, Allah told us in a hadith qudsi (words of inspiration from Allah, expressed by the mind and tongue of Prophet Muhammad (p)):

"I am in the Company of my servant as long as he remembers Me and his lips move because of his remembrance of Me."

What better company could one wish for oneself? Muslims tend to go so deeply into their business affairs that these worldly matters become a hindrance to worshipping Allah and seeking tazkiyah for their hearts. There is no justification for allowing business or family affairs to obstruct the spiritual development of tazkiyah. An example of this is related in the Holy Qur'an. Allah said in Surah al Fat-h (the Victory):

"The desert Arabs who lagged behind will say to you: 'we were engaged in (looking after) our flocks and herds, and our families; do then ask forgiveness for us.' They say with their tongues what is not in their hearts." Qur’an, 48:11.

Obligations, including prayers, are the means to accomplish thikru Allah, as Allah ordained:

"And establish regular prayer for remembering (praising) Me." Qur’an, 20:14.

Even pilgrimage (hajj) is designed to accomplish thikr. We read about it when Allah says:

"And proclaim the pilgrimage among men; they will come to you on foot and (mounted) on every kind of camel, lean on account of journeys through deep and distant mountain highways, so that they may witness the benefits (provided) for them, and celebrate the name of Allah through the days appointed." Qur’an, 22:27-28.

This is a brief discussion of the importance of tazkiyah and thikru Allah in Islam. This matter is often neglected in the lives of many Muslims today. For those who seek to tread the way of the prophet (p), it is incumbent on them to adapt their lives to include this spiritual component. This in turn contributes to the purification of inner-self, tazkiyah, one of the essential fundaments of Islamic development and the well-being of mankind. Just as the body needs food to stay healthy, the soul too needs its spiritual nourishment. Muslims today must earnestly consider tazkiyah as the number one priority in their lives.
