question #1 Sahih Muslim 535d, Book 5, Hadith 37 : What is the correct position of the hands during bowing in prayer according to Islamic teachings?

I said prayer by the side of my father. When I bowed I intertwined my fingers and placed them between my knees. He struck my hands. When he completed the prayer he said: We used to do that but then were commanded to lift (our palms) to the knees.
