Hadith 868
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، حَدَّثَنَا الأَعْمَشُ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، وَالأَسْوَدِ، عَنْ عَبْدِ اللَّهِ، قَالَ إِذَا رَكَعَ أَحَدُكُمْ فَلْيَفْرِشْ ذِرَاعَيْهِ عَلَى فَخِذِهِ وَلْيُطَبِّقْ بَيْنَ كَفَّيْهِ فَكَأَنِّي أَنْظُرُ إِلَى اخْتِلاَفِ أَصَابِعِ رَسُولِ اللَّهِ صلى الله عليه وسلم .
‘Abd Allah (b. Masud) said:
When any of you bows, he should spread his arms on his thighs and clap both his palms (Placing them between the knees), as if I am seeing the variation of the fingers of the Messenger of Allah(ﷺ).
