Hadith 4045

(حديث مرفوع) حَدَّثَنَا ابْنُ نُمَيْرٍ ، حَدَّثَنَا الْأَعْمَشُ ، عَنْ إِبْرَاهِيمَ ، عَنِ الْأَسْوَدِ ، قَالَ : دَخَلْتُ أَنَا وَعَلْقَمَةُ عَلَى عَبْدِ اللَّهِ بْنِ مَسْعُودٍ ، فَقَالَ : " إِذَا رَكَعَ أَحَدُكُمْ ، فَلْيُفْرِشْ ذِرَاعَيْهِ فَخِذَيْهِ ، فَكَأَنِّي أَنْظُرُ إِلَى اخْتِلَافِ أَصَابِعِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الصَّلَاةِ " .
It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that when any one of you performs ruku', he should spread his arms over his thighs and join his two palms together. It is as if I can still see the Prophet's (peace and blessings be upon him) fingers spread apart. Saying this, he demonstrated by joining his two palms together in the position of ruku'. (This ruling has been abrogated.)
