I stood to pray with the Prophet ﷺ and positioned myself on his left. He reached behind himself with his hand, took hold of my upper arm, or my hand, and moved me to his right side.
حدثنا أبو سعيد مولى بني هاشم وعبد الصمد المعنى قالا حدثنا ثابت حدثنا عاصم عن الشعبي
قمت أصلي مع النبي ﷺ فقمت عن يساره فقال بيده من ورائه حتى أخذ بعضدي أو بيدي حتى أقامني عن يمينه
Its isnad is sahih. Thabit is Ibn Yazid al-Ahwal. Aasim is Ibn Sulayman al-Ahwal. Abu Saeed, the freed slave of Banu Hashim, is Abdul-Rahman bin Abdullah bin Ubayd al-Basri, and he is trustworthy, one of the teachers of Ahmad. The hadith is a repetition of 2326.
