Jābir ibn ‘Abdullah (may Allah be pleased with him and his father) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "Beware of oppression, for oppression will be layers of darkness on the Day of Judgment; beware of stinginess, as stinginess ruined those before you. It incited them to shed their blood and regard the unlawful as lawful."

Abu Mūsa (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Verily, Allah gives respite to the oppressor, but when He seizes him, He does not release him." Then, he recited: {Such is the seizing of your Lord when He seizes the towns that are given to wrongdoing; His seizing is surely painful and severe.} [Surat Hūd: 102]"

Ibn ‘Abbās (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him), as part of what he narrated from his Lord, said: "Allah has written down the good deeds and the bad ones. Then, He explained that: He who intends a good deed and does not do it, Allah writes it down with Himself as a full good deed; and if he intends it and does it, Allah writes it down with Himself as ten good deeds to seven hundred times, or many times over. Yet, if he intends a bad deed and does not do it, Allah writes it down with Himself as a full good deed. But, if he intends it and does it, Allah writes it down as one bad deed."

Ibn Mas‘ūd (may Allah be pleased with him) reported: A man said: "O Messenger of Allah, will we be punished for what we did during jāhiliyyah (the pre-Islamic period of ignorance)?" He said: "He who does good in Islam will not be punished for what he did during jāhiliyyah, and he who commits evil in Islam will be punished for the previous and later deeds."

Ibn ‘Abbās (may Allah be pleased with him) reported: A group of polytheists, who went to excess in killing and committing illegal sexual intercourse, came to Muhammad (may Allah's peace and blessings be upon him) and said: "What you say and invite people to is indeed good. If only you could tell us whether there is an expiation for what we did. Thereupon, it was revealed: {and those who do not invoke besides Allah, another god, and who do not kill a soul whom Allah has forbidden, except in the course of justice, and who do not commit adultery} [Surat al-Furqān: 68]. And the following verse was revealed: {Say [Allah says]: "O My slaves who have transgressed against themselves, do not despair of Allah's mercy."} [Surat az-Zumar: 53]

Hakīm ibn Hizām (may Allah be pleased with him) reported: I said: "O Messenger of Allah, before embracing Islam, I used to do good deeds, like giving in charity, manumitting slaves, and upholding kinship ties. Shall I be rewarded for those deeds?" The Prophet (may Allah’s peace and blessings be upon him) replied: "You have embraced Islam along with your past good deeds."

Anas ibn Mālik (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Allah does not wrong a believer in a good deed; he will be given on account of it in this world and will be rewarded for it in the Hereafter. As for the disbeliever, he will be given the reward for the good deeds he has not performed for the sake of Allah in this world, and when he comes to the Hereafter, there will be no good deed for which he can be rewarded."

Anas ibn Mālik (may Allah be pleased with him) reported: I heard the Messenger of Allah (may Allah's peace and blessings be upon him) say: "Allah Almighty said: 'O son of Adam, so long as you call upon Me and ask of Me, I shall forgive you for what you have done, and I shall not mind. O son of Adam, were your sins to reach the clouds of the sky and were you then to ask forgiveness of Me, I shall forgive you. O son of Adam, were you to come to Me with sins nearly as great as the earth and were you then to meet Me, ascribing no partner to Me, I shall bring you forgiveness nearly as great as it is.'"

Abu Hurayrah (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him), narrating from his Almighty Lord, said: "A servant committed a sin and said: 'O Allah, forgive my sin,’ and Allah Almighty said: ‘My servant committed a sin and then realized that he has a Lord Who forgives sins and punishes for sins.' Then, he committed a sin again and said: ‘My Lord, forgive my sin,’ and Allah Almighty said: ‘My servant committed a sin and then realized that he has a Lord Who forgives sins and punishes for sins.’ He again committed a sin and said: ‘My Lord, forgive my sin,’ and Allah Almighty said: ‘My servant committed a sin and then realized that he has a Lord Who forgives sins and punishes for sins. Do whatever you wish, for I have forgiven you.'"

‘Ali reported: Indeed I am a man who, when hearing a Hadīth from the Messenger of Allah (may Allah's peace and blessings be upon him), Allah benefitted me thereby as much as He willed for me to benefit thereby. When a man from his Companions narrates some Hadīth to me, I ask him to swear upon it, when he swears, I believe him. And Abu Bakr narrated to me - and Abu Bakr told the truth; he said: I heard the Messenger of Allah (may Allah's peace and blessings be upon him) say: "There is no man who commits a sin, then gets up and performs Tahārah (ritual purification), then performs prayer, then seeks forgiveness from Allah, except that Allah forgives him." Then, he recited this verse: {And those who, when they commit a shameful act or wrong themselves, remember Allah and seek forgiveness for their sins.} [Surat Āl ‘Imrān: 135]

Abu Mūsa (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Verily, Allah Almighty extends His Hand during the night so the sinner of the day may repent, and He extends His Hand during the day so the sinner of the night may repent until the sun rises from its west."

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Our Lord, Glorified and Exalted, descends every night to the lowest heaven when the last third of the night remains and says: ‘Who supplicates Me so that I may answer him? Who asks Me so that I may give him? Who seeks forgiveness from Me so that I may forgive him?'"
