It is narrated from Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) went to the people of Banu Amr bin Awf to make peace among them, and the time for prayer came. The mu’adhdhin came to Sayyiduna Abu Bakr as-Siddiq (may Allah be pleased with him) and said:“If you will lead the prayer, I will say the takbir?”He said:“Alright.”So Sayyiduna Abu Bakr (may Allah be pleased with him) began the prayer, and the Messenger of Allah (peace and blessings be upon him) arrived while the people were praying. So he (peace and blessings be upon him) made his way through the rows until he stood in the first row. The people started clapping. Sayyiduna Abu Bakr (may Allah be pleased with him) would not pay attention to anything during the prayer, until the people started clapping loudly. Then Sayyiduna Abu Bakr (may Allah be pleased with him) saw the Messenger of Allah (peace and blessings be upon him) and intended to step back. The Messenger of Allah (peace and blessings be upon him) gestured:“Stay in your place.”So Sayyiduna Abu Bakr (may Allah be pleased with him) raised both his hands and thanked Allah for the command of the Messenger of Allah (peace and blessings be upon him) that he should remain as imam. Then Sayyiduna Abu Bakr (may Allah be pleased with him) stepped back, and the Messenger of Allah (peace and blessings be upon him) moved forward and completed the prayer. Then he said:“O Abu Bakr! Why did you not remain in your place when I gestured to you?”Sayyiduna Abu Bakr (may Allah be pleased with him) said:“It does not befit the son of Abu Quhafah to lead the prayer in the presence of the Messenger of Allah (peace and blessings be upon him).”Then the Messenger of Allah (peace and blessings be upon him) said to the people:“Why did you clap so much? If something happens to someone in the prayer, he should say ‘Subhan Allah’; the people will look towards him. And clapping is for women.”

It is narrated from Nafi‘ that Sayyiduna Abdullah bin Umar (may Allah be pleased with them) would not turn his face during prayer.

It is narrated from Abu Ja'far Qari that I was praying and Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) was behind me, I was not aware. When I saw him, I suppressed myself, and he restrained me (i.e., forbade me from turning).
