Narrated Ibn `Umar from Hafsa his sister: That the Prophet had said to her, "`Abdullah is a pious man."
حَدَّثَنَا يَحْيَى بْنُ سُلَيْمَانَ، حَدَّثَنَا ابْنُ وَهْبٍ، عَنْ يُونُسَ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ، عَنْ أُخْتِهِ، حَفْصَةَ أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ لَهَا " إِنَّ عَبْدَ اللَّهِ رَجُلٌ صَالِحٌ " .
