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
مسند امام احمد بن حنبل · Hadith 4045
It was narrated that al-Aswad said: 'Alqamah and i entered upon 'Abdullah bin Mas'ood and he said: When one of you bows, let him put his forearms on his thighs. It is as if I can see the interlaced fingers of the Messenger of Allah (PBUH) in prayer.
