X"I heard Abu Uthman narrate that Ibn Mas'ud said: 'The Prophet (ﷺ) saw me when I had placed my left hand on my right in prayer. He took hold of my right hand and placed it on my left.'"
Sunan an-Nasa'i Book 11, Hadith 13
← Previous Hadith "Alqamah bin Wa'il told us that his father said: "I saw the Messenger of Allah (ﷺ), when he was standing in prayer, holding his left hand with his right.'"

Sunan an-Nasa'i Book 11, Hadith 12 Next Hadith → "I said: 'I am going to watch how the Messenger of Allah (ﷺ) prays.' So I watched him and he stood and said the takbir, and raised his hands until they were in the level with his ears, then he placed his right hand over his left hand, wrist and lower forearm. When he wanted to bow he raised his hands likewise. Then he prostrated and placed his hands in level with his ears. Then he sat up and placed his left leg under him; he put his left hand on his left thigh and knee, and he put the edge of his right elbow on his right thigh, then he held two of his fingers together and made a circle, and raised his forefinger, and I saw him moving it and supplicating with it."
