Mishkat al-Masabih 1106
'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.)
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
