The Repentance of Thought

Whoever’s ultimate destination is the Fire has failed to attain the true nature and purpose of the intellect. Allah, the Exalted, says: “They will say, ‘Had we but listened or reasoned, we would not have been among the inhabitants of the Blaze.’” (67:10). Al-Tirmidhi narrated a report in which a man said to the Messenger of Allah, peace and blessings be upon him, “How intelligent that Christian man is!” The Messenger of Allah, peace and blessings be upon him, replied: “The disbeliever has no intellect. Have you not heard the statement of Allah: ‘Had we but listened or reasoned, we would not have been among the inhabitants of the Blaze’?”

The reason for this is that the true function of the intellect is to remove the veil from inner insight by directing a person to observe and reflect upon Allah’s creation until they realize that this universe was not created in vain and that its Originator is Allah, the Most High. Through this reflection, the intellect comes to recognize the truth, rise above the constraints of familiarity and convention, turn away from falsehood, and be guided by the light of revelation.

Accordingly, the intellect cannot serve as an independent source of knowledge, certainty, or the final arbiter of truth, as the philosophers of modernity claimed. Indeed, postmodern philosophers themselves criticized this assumption, acknowledging that knowledge is shaped by numerous factors external to the intellect, thereby undermining the claim of absolute confidence in reason alone. Nevertheless, their conception of the intellect remained detached from the supreme purpose for which Allah created it.

In Islamic doctrine, however, the intellect is a faculty of perception that Allah has endowed human beings with, enabling them to distinguish truth from falsehood, infer the existence and oneness of Allah, comprehend revelation, and recognize the truthfulness of His message. Yet the intellect neither reaches its maturity nor fulfills its purpose except through the guidance of revelation. Likewise, revelation cannot be properly understood except through the intellect. For this reason, Imam al-Ghazali likened the intellect to eyesight and revelation to the sun: just as eyesight is of no benefit in darkness, the intellect cannot arrive at the complete truth without the light of revelation; and just as sunlight is of no benefit to the blind, revelation bears fruit only through an intellect that perceives and understands.

This meaning is further affirmed in the saying of Allah, the Exalted: “Those who shun the worship of false deities and turn in repentance to Allah shall have the glad tidings. So give glad tidings to My servants—those who listen attentively to what is said and follow the best of it. They are the ones whom Allah has guided, and they are the people of understanding.” (39:17–18). Guidance is attained only through the meeting of two elements: an active cause and a receptive recipient. The active cause is indicated by Allah’s statement, “They are the ones whom Allah has guided,” while the receptive recipient is indicated by His statement, “They are the people of understanding.” Allah then praises them for following the best of what they hear, describing them as people of discernment, sound judgment, and critical insight who distinguish guidance from misguidance and wisdom from illusion. This also indicates that following the best of what one hears is among the means by which Allah grants His guidance.

Directing the intellect toward the realization of servitude to Allah—by employing it to know Allah, understand revelation, and distinguish truth from falsehood—is the primary function for which it was created. The fruit of fulfilling this function is that it opens the heart to the light of divine guidance.

This meaning is reflected in a report concerning Umar ibn al-Khattab (may Allah be pleased with him). When he was asked, “Did you not possess intellects when you opposed the Messenger, peace be upon him?” he replied, “Yes, we had intellects, but we did not have guidance.”

For the intellect to attain its intended fruit, it must undergo sincere repentance—the repentance of thought. This consists of correcting the foundation upon which knowledge is formed and reconstructing one’s worldview upon the basis of divine guidance, which alone represents the truth.

The repentance of thought rests upon two fundamental maxims.

The first maxim is adhering to foundational principles that establish firmness upon the truth and the straight path. Among the most important of these are the following:

First: Whoever does not believe in Allah has no true intellect. Allah, the Exalted, says: “He said, ‘The Lord of the East and the West and whatever is between them, if only you would reason.’” (26:28). And He also says: “Fie upon you and upon what you worship besides Allah! Will you not then reason?” (21:67)

Second: Strengthening the foundation upon which faith is built, namely, submission to self-evident truths, foremost among them the existence of Allah, the Exalted. Allah says: “Their messengers said, ‘Can there be any doubt concerning Allah?’” (14:10). A subtle rhetorical point in this verse is the omission of the indirect object. Allah did not say, “Their messengers said to them,” but rather, “Their messengers said.” This indicates that the messengers did not direct their response exclusively to the questioners, for the existence of Allah is a self-evident reality that is not a legitimate subject of doubt. Whoever questions it has departed from the proper function of the intellect. Accordingly, the believer must expel every residue of doubt implanted by secular education, cultural conditioning, or life in a materialistic society, for such residues act as barriers that cloud the purity of faith.

Third: Striving against intellectual dullness and the loss of spiritual insight caused by the dominance of familiarity and habit over perception. This is achieved by linking reflection upon creation with gratitude for Allah’s blessings and remembrance of life’s ultimate purpose. Allah says: “Our Lord, You have not created this in vain. Glory be to You, so protect us from the punishment of the Fire.” (3:191)

Fourth: Directing contemplation toward recognizing the greatness of the Creator in order to strengthen one’s trust in Him. Through reflection, the servant comes to appreciate the perfection of Allah’s knowledge, the vastness of His wisdom, and the precision and harmony of His creation. Allah says: “You do not see any inconsistency in the creation of the Most Merciful. So look again: do you see any flaw?” (67:3). He also says: “Blessed is Allah, the Best of creators.” (23:14). And: “Who perfected everything that He created.” (32:7). And: “And with Him are the keys of the unseen; none knows them except Him. And He knows what is on the land and in the sea. Not a leaf falls but that He knows it. And no grain is there within the darknesses of the earth and no moist or dry [thing] but that it is [written] in a clear record.” (6:59)

The second principle of the repentance of thought is following what is best. This is an essential characteristic of the believing servant, reflecting a critical faculty grounded in the careful pursuit and thorough examination of the truth. Its aim is to discern the correct meaning and determine the most appropriate application of the truth according to the circumstances and realities of one’s time and place. Among the clearest manifestations of following what is best is the sound application of the teachings of revelation to reality in a manner that fulfills their objectives and embodies divine guidance in people’s lives.

The practical stage consists of enriching one’s inner dialogue through constructive rational deliberation, leaving the servant with no room to abandon worship or neglect righteous deeds once conclusive proofs have been established. A servant should not cease striving in obedience merely because they do not feel inclined toward it or have not yet tasted the anticipated sweetness of faith. The inclination toward righteous deeds and the experience of the sweetness of faith are gifts from Allah, bestowed upon those who are sincere in fulfilling His commands and who persevere in obedience, as is the case with remembrance, prayer, and love for the Prophet, peace and blessings be upon him.

For this reason, the servant should remind themselves that within these deeds lie their comfort and success, in fulfillment of the words of Allah, the Exalted: “Surely, in the remembrance of Allah do hearts find rest.” (13:28). They should also recognize that these deeds are a means to true success, as Allah, the Exalted, says: “Certainly, the believers have succeeded.” (23:1)

Thus, the servant compels themselves, strives against their own inclinations, and urges themselves to hasten toward these deeds, placing their trust in Allah’s promise and hoping that He will grant them the sweetness of faith that He has promised to those who are sincere.

This logical progression represents the proper way of employing the intellect for the purpose for which it was created. It begins with establishing sound foundations, followed by strengthening conviction, affirming the truth, and then persevering in righteous action until the servant becomes worthy of Allah’s gift: the sweetness of faith. The Prophet, peace and blessings be upon him, referred to this divine gift when he said: “There are three qualities: whoever possesses them will taste the sweetness of faith: that Allah and His Messenger are more beloved to him than anything else; that he loves a person only for the sake of Allah; and that he would hate to return to disbelief after Allah has saved him from it, just as he would hate to be thrown into the Fire.” Thus, he identified the sweetness of faith as a fruit attained after its causes have been fulfilled. For this reason, one of the righteous predecessors said: “I struggled with my self for twenty years to attain sweetness in prayer; then I enjoyed it for twenty years.”

This illustrates that striving against the self precedes the sweetness of worship. Whoever patiently disciplines themselves to obey Allah will ultimately be granted the sweetness of faith, the delight of drawing near to Him, and the joy of sincere devotion.
