Musannaf Ibn Abi Shaybah 3145 — Whether a man turns to his right

Wasi' bin Habban said: I was praying while Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) was sitting, leaning against the wall of the qiblah. After praying, I turned to my left side, and he said: "Why did you not turn to your right side?" I said: "No reason, except that I saw you, so I got up and came towards you." He said: "You did well. Some people say that you are to get up towards the right side (they consider it necessary). When you have prayed, turn to the right if you wish, and to the left if you wish."
