أَخْبَرَنِي أَحْمَدُ بْنُ سَعِيدٍ الرِّبَاطِيُّ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ، قَالَ أَنْبَأَنَا عَمْرٌو، - وَهُوَ ابْنُ أَبِي قَيْسٍ - عَنِ الزُّبَيْرِ بْنِ عَدِيٍّ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، وَعَلْقَمَةَ، قَالاَ صَلَّيْنَا مَعَ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ فِي بَيْتِهِ فَقَامَ بَيْنَنَا فَوَضَعْنَا أَيْدِيَنَا عَلَى رُكَبِنَا فَنَزَعَهَا فَخَالَفَ بَيْنَ أَصَابِعِنَا وَقَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَفْعَلُهُ .
It was narrated that 'Alqamah and Al-Aswad said: "We prayed with Abdullah bin Mas'ud in his house. He stood between us and we placed our hands on our knees, but he took them off and made us interlace our fingers, and said: "I saw the Messenger of Allah (PBUH) do that.'" Translation Not Available
