A man from the Juhaina tribe, Aghar, used to narrate to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he heard the Messenger of Allah (peace and blessings be upon him) saying: O people! Repent to your Lord, for indeed I repent to Allah one hundred times in a single day.

Sayyiduna Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: By Allah, indeed I seek forgiveness from Allah and turn to Him in repentance more than seventy times in a day.

Sayyiduna Abu Burdah (may Allah be pleased with him) narrates from a Companion that the Messenger of Allah (peace and blessings be upon him) said: O people! Repent to Allah and seek forgiveness from Him, for indeed I repent to Allah and seek forgiveness from Him one hundred times each day. The narrator asked: Should this supplication be counted twice or once: "Allahumma inni astaghfiruka, Allahumma inni atubu ilayk" (O Allah! Indeed I seek Your forgiveness, indeed I turn to You in repentance)? He replied: This is counted as once.

(In another chain) It is narrated that he used to do it one hundred times or more than one hundred times.

Syedna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: When a believer commits a sin, a black spot appears on his heart. If he repents and seeks forgiveness, his heart becomes bright and polished. But if he continues to sin, the spots increase until his heart is completely covered with rust, as Allah Almighty mentioned in this verse: Never! Rather, the rust has covered their hearts because of what they used to earn.

It is narrated from Harith bin Suwaid, he says: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrated two hadiths to us, one was his own saying and the other was a hadith of the Messenger of Allah (peace and blessings be upon him). He himself said: Indeed, a believer considers his sins as if he is standing beneath a mountain and fears that the mountain may fall upon him, whereas a wicked person considers his sins like a fly that sits on his nose and he just swats it away like this. The Messenger of Allah (peace and blessings be upon him) said: Allah Almighty is more pleased with the repentance of a servant than that person who is in a barren and deadly wilderness, with him is his riding animal on which are loaded his food, drink, provisions, and other necessities. Then that riding animal is lost from him, he searches for it until he is overtaken by death, then he says: Now I will return to the place where I lost my riding animal, and going there, he dies. Then he returns to his place and sleeps there, and when he wakes up, his riding animal is standing beside him, and on it are his food, drink, provisions, and other necessities.

A similar hadith is narrated from Sayyiduna Nu’man bin Bashir (may Allah be pleased with him), but its wording is slightly different: Thus, the mount was standing by him and pulling its reins. The happiness that Allah Almighty feels due to His servant’s repentance, this man was not happier than that.

Syedna Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: When a man's mount is lost, does he rejoice upon finding it? The people said: Yes, O Messenger of Allah! He (peace and blessings be upon him) said: By Him in Whose hand is the soul of Muhammad (peace and blessings be upon him)! Allah is more pleased with His servant's repentance than any of you is upon finding his lost mount.

It is narrated from Sayyiduna Abu Musa (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Verily, Allah Almighty stretches out His hand at night so that the one who sinned during the day may repent, and He stretches out His hand during the day so that the one who sinned at night may repent. This will continue until the sun rises from the west.

It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Verily, Allah Almighty says: O My servants! All of you are sinners, except the one whom I grant well-being, so seek forgiveness from Me, I will forgive you. Whoever realizes that I have power over forgiveness and then seeks forgiveness from Me because of My power, I will forgive him and I do not care. O My servants! All of you were astray, except the one whom I have guided, so ask Me for guidance, I will guide you. All of you were poor, except the one whom I have enriched, so ask Me, I will provide for you. If the living and the dead among you, the first and the last, the moist and the dry, were to gather together upon the heart of the most pious man among My servants, it would not increase My dominion by even as much as the wing of a mosquito. Likewise, if the living and the dead among you, the first and the last, the moist and the dry, were to gather together and every supplicant were to ask for whatever he desired, and I were to give each supplicant what he asked for, it would not decrease what is with Me except as much as a needle decreases the sea when it is dipped into it and then taken out. This is because I am Generous, Majestic, Rich; I do whatever I will. My giving is My word, My punishment is My word. When I intend a thing, I only say to it: Be, and it is.
