Ali from his father from Ibn Abi Umayr from Hammad from Al-Halabi from Abu Abdillah عليه السلام: Imam عليه السلام was asked about a man who needs something while he is in prayer. Imam عليه السلام said: "He should gesture with his head and signal with his hand. And a woman, if she needs something while she is praying, should clap with her hands." He (al Halabi) said: “And I asked Imam عليه السلام about a man who yawns and stretches during the prayer”. Imam عليه السلام said: "It is from Shaytan, and he will not be able to control it."
