عَنِ الْأَسْوَدِ وَعَلْقَمَةَ عَنْ عَبْدِ اللَّهِ (بْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ) قَالَ: إِذَا رَكَعَ أَحَدُكُمْ فَلْيَفْرُشْ ذِرَاعَيْهِ فَخِذَيْهِ وَلْيَحْنِأْ ثُمَّ طَبَّقَ بَيْنَ كَفَّيْهِ، فَكَأَنِّي أَنْظُرُ إِلَى اخْتِلَافِ أَصَابِعِ رَسُولِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ، قَالَ: ثُمَّ طَبَّقَ بَيْنَ كَفَّيْهِ فَأَرَاهُمَا
It is narrated from Aswad and Alqamah that: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: When any of you performs ruku‘, he should spread his arms over his thighs and bend his back. Then he interlaced his fingers and said: It is as if I am seeing the fingers of the Messenger of Allah (peace and blessings be upon him) that they were interlaced with each other. Then he interlaced his fingers and showed them.
