Sayyiduna Wa'il bin Hujr (may Allah be pleased with him) said: I said: I will surely watch the Messenger of Allah (peace and blessings be upon him) to see how he (peace and blessings be upon him) prays. So I watched him. He (peace and blessings be upon him) said the takbir and raised his hands up to the level of his ears, then placed his right hand on the back of his left hand, between the wrist and the forearm. Then when he intended to bow, he raised his hands in the same way and placed his hands on his knees. Then he raised his head and raised his hands in the same way. Then he prostrated and placed his palms level with his ears. Then he sat, spread out his left foot and placed his left palm, and placed the edge of his right elbow on his right thigh. Then he closed two of his fingers and made a ring, then raised his finger, and I saw him (peace and blessings be upon him) moving it, supplicating with it. Then after that I came in the winter season and saw that the people were wearing heavy garments and moving their hands from beneath their garments.
