sahih· Darussalam

It was narrated from ‘Abdur-Rahman bin Ka’b bin Malik that his father said that when Allah accepted his repentance, he fell down prostrate.

حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ كَعْبِ بْنِ مَالِكٍ، عَنْ أَبِيهِ، قَالَ لَمَّا تَابَ اللَّهُ عَلَيْهِ خَرَّ سَاجِدًا ‏.‏
