وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم: «إِنَّ الْعَبَدَ إِذَا اعْتَرَفَ ثُمَّ تَابَ تَابَ الله عَلَيْهِ»
'A’isha reported God’s messenger as saying, "When a servant acknowledges his sin and repents, God forgives him.” (Bukhari and Muslim.)
