Sayyiduna Wa'il bin Hujr (may Allah be pleased with him) narrates that he performed prayer behind the Prophet Muhammad (peace and blessings be upon him). The Prophet (peace and blessings be upon him) placed his right blessed hand over his left blessed hand. When he said «ولا الضالین» , he said Ameen. At the end of the prayer, he turned (for salam) to his right side and to his left side (i.e., twice).
