عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ قَالَ: بِتُّ فِي بَيت خَالَتِي مَيْمُونَةَ فَقَامَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُصَلِّي فَقُمْتُ عَنْ يَسَارِهِ فَأَخَذَ بِيَدِي مِنْ وَرَاءِ ظَهْرِهِ فَعَدَلَنِي كَذَلِكَ مِنْ وَرَاءِ ظَهره إِلَى الشق الْأَيْمن

'Abdallah b. ‘Abbas said

When I was spending a night in the house of my maternal aunt Maimuna God’s Messenger stood up and prayed. I stood at his left side, and he, taking my hand behind his back, directed me thus* behind his back to his right side. *'Abdallah would use a gesture to indicate how it was done.(Bukhari and Muslim.)
