Silsilat al-Ahadith al-Sahihah

Lady Aisha (may Allah be pleased with her) says: I said: O Messenger of Allah! Ibn Jud'an used to maintain ties of kinship during the days of ignorance and feed the poor; will these good deeds benefit him? The Prophet (peace and blessings of Allah be upon him) said: "No, Aisha! He never said, even for a single day: O my Lord! Forgive my sins on the Day of Resurrection."

Sayyiduna Abu Sa‘id Khudri (may Allah be pleased with him) narrates that the Messenger (peace and blessings of Allah be upon him) said: "When a person accepts Islam and his Islam becomes good, then whatever good deed he had done, Allah Almighty writes it down (and preserves it), and whatever sin he had committed is erased. Then (after that, from Allah Almighty) the further reward is that one good deed takes the form of ten to seven hundred times, and as for the matter of a sin, it remains only one, unless Allah Almighty also forgives that."

Lady Umm Salamah (may Allah be pleased with her) says: I said to the Prophet (peace and blessings of Allah be upon him): Hisham bin Mughirah used to maintain ties of kinship, host guests, free slaves, feed people, and if he had lived in the time of Islam, he would have become a Muslim as well. Will these deeds benefit him? The Prophet (peace and blessings of Allah be upon him) said: "No, he used to do so for worldly purposes, for his fame and reputation, and for flattery and praise. He never said even for a single day: O my Lord! Forgive my sins on the Day of Resurrection."

Sayyiduna Hakim bin Hizam (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings of Allah be upon him) said: "You have accepted Islam along with all the good deeds you have done."
