‘Uqba b. ‘Amir reported God’s messenger as saying, “One who does evil deeds and afterwards does good deeds is like a man who was wearing a tight coat of mail which choked him, then did a good deed and a ring was loosened, then did another and another was loosened, so that it fell at last to the ground.”
Narrated Ibn ‘Abbas reported God’s messenger as saying, “God records the good deeds and the evil deeds. If anyone intends to do a good deed but does not do it, God enters it for him in His record as a complete good deed:
and if he intends to do a good deed and does it, God enters it for him in His record as ten to seven hundred and many more times as much. If anyone intends to do an evil deed and does not do it, God enters it for him in His record as a complete good deed; but if he intends to do it and does it, God records it for him as one evil deed.”
Abud Darda’ told of his hearing the Prophet delivering a discourse on the pulpit and saying, “He who fears standing before his Lord will have two paradises.” He asked, “Even if he commits fornication and even if he steals, messenger of God?” but he said a second time, “He who fears standing before his Lord will have two paradises.” He asked a second time, “Even if he commits fornication and even if he steals, messenger of God?” and he said a third time, “He who fears standing before his Lord will have two paradises.” He asked a third time, “Even if he commits fornication and even if he steals, messenger of God?” to which he replied, “Even in spite of Abud Darda’.”
Abu Sa'id reported God’s messenger as saying, “When a man accepts Islam sincerely God removes from him every sin he has previously committed. After that there will be requital, a good deed getting ten to seven hundred times as much and many times more, and an evil deed getting a punishment equivalent to it, unless God overlooks it.”
