Hadith Commentary:
➊
The Messenger of Allah sallallahu alayhi wa sallam was extremely pleased at the revelation of this verse. Thus, Anas radi Allahu anhu narrates that this verse was revealed when he was returning to Madinah from Hudaybiyyah. He said:
“This verse has been revealed to me, which is dearer to me than all the wealth of the earth.”
The noble Companions radi Allahu anhum ajma‘in said:
“O Messenger of Allah sallallahu alayhi wa sallam! Congratulations, congratulations! Allah Ta‘ala has clarified for you what He will do with you, but what will be the case with us?” At that moment, these verses were revealed:
“So that He may admit the believing men and believing women to gardens beneath which rivers flow, wherein they will abide forever, and remove from them their misdeeds. And that is, with Allah, a great success.” (, and Jami‘ at-Tirmidhi, Tafsir al-Qur’an, Hadith: 3263)

The conquest of Makkah is a worldly blessing, and along with it, the mention of the hereafter’s blessing—namely, forgiveness—has been made, because the conquest of Makkah became the cause for Hajj, and Hajj (pilgrimage) is a great means for the forgiveness of sins. Then, after the manifest victory, people began entering Islam in crowds, and the work of inviting to Islam became widespread.
Through this, the purpose of your life was fulfilled.
Wallahu al-musta‘an (And Allah is the One whose help is sought).

Hadith Commentary: Benefits and Issues: The application of the word "sin" (dhamb) is very broad. Any action that is beneath someone's dignity or status, or is contrary to what is preferable (khilaf awla), is also called a "sin" (dhamb), and beyond that, its application even extends to disbelief and polytheism (kufr and shirk). Here, what is meant are those actions that were beneath your lofty and exalted status, or were contrary to what was preferable. And according to Qadi Sulaiman rahimahullah, what is meant are those accusations that were leveled against you before and after the migration (hijrah). For details, see Rahmatul-lil-Alameen. Pir Karam Shah has transmitted this meaning, but did not mention the name of Qadi Sahib. (Zia-ul-Qur’an, vol. 5, pp. 532–533)

To interpret it this way is not free from affectation, because the incident of Musa alayhis salam—“And they have a sin against me, so I fear that they will kill me” (ash-Shu‘ara: 14) —has been used as evidence, and Musa alayhis salam himself described this sin as wrongdoing (zulm) and sought forgiveness: “He said: ‘My Lord, indeed I have wronged myself, so forgive me.’ So He forgave him. Indeed, He is the Most Forgiving, Most Merciful.” (Surah al-Qasas: 16)

Therefore, the fact that the Prophet sallallahu alayhi wa sallam endured so much hardship in worship was as gratitude for forgiveness, that when Allah Ta‘ala has bestowed such grace and favor upon me that He has forgiven all my sins, then I should express gratitude for this blessing and favor.

From this it is understood that just as gratitude is expressed verbally, it is also expressed through action, as is the statement of Allah Ta‘ala: “Work, O family of Dawud, in gratitude.” (Surah Saba: 13)
