Is it established that the Prophet (peace and blessings be upon him) would place his left hand in his left knee during the sitting between the two prostrations?

Question:
May Allah reward you, Honorable Shaykh. This questioner asks: Is it established that the Prophet (peace and blessings be upon him) would place his left hand in his left knee, put his right hand on his thigh, and point with his index finger, and that this is in the sitting between the two prostrations?

Answer:
Regarding placing the hand in the knee, I do not know of any report that this was done. However, he places his hand on his knee, on top of it. This has passed by you; there is no harm in it. He places his palms on his knees.
