One night I stood to the left of the Prophet ﷺ in the prayer but he caught hold of me by the hand or by the shoulder (arm) till he made me stand on his right and beckoned with his hand (for me) to go from behind (him). (Al-Kashmaihani [??] , Fath-ul-Bari).  

عَنْ يَسَارِ النَّبِيِّ ﷺ فَأَخَذَ بِيَدِي أَوْ بِعَضُدِي حَتَّى أَقَامَنِي عَنْ يَمِينِهِ وَقَالَ بِيَدِهِ مِنْ وَرَائِي
