Musannaf Ibn Abi Shaybah 2563 — Those who used to press their hands

Mughirah said: I asked Ibrahim, "Did Abdullah, in ruku', place his hands one over the other between his legs and spread his forearms over his thighs?" He said, "Yes." I said, "Should I also do that?" He said, "Sayyiduna Umar (may Allah be pleased with him) used to place his hands on his knees."
