حَدَّثَنَا أَبُو سَعِيدٍ مَوْلَى بَنِي هَاشِمٍ وَعَبْدُ الصَّمَدِ الْمَعْنَى قَالَا حَدَّثَنَا ثَابِتٌ حَدَّثَنَا عَاصِمٌ عَنِ الشَّعْبِيِّ عَنِ ابْنِ عَبَّاسٍ قَالَ قُمْتُ أُصَلِّي مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقُمْتُ عَنْ يَسَارِهِ فَقَالَ بِيَدِهِ مِنْ وَرَائِهِ حَتَّى أَخَذَ بِعَضُدِي أَوْ بِيَدِي حَتَّى أَقَامَنِي عَنْ يَمِينِهِ
مسند امام احمد بن حنبل · Hadith 2413
It was narrated that Ibn 'Abbas (RA) said: I got up to pray with the Prophet (PBUH) and I stood on his left. He reached back with his hand and took hold of my upper arm - or my arm - and made me stand on his right.
