Sahih Ibn Khuzaymah 698 — 217 Chapter: Placing the Right Thigh over

It is narrated from Sayyiduna Wa’il bin Hujr al-Hadrami (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) said « اللهُ أَكْبَرُ », he raised both his hands, and when he bowed (ruku‘), and when he raised his head from ruku‘ (he performed the raising of the hands), and when he prostrated, he said: “Like this,” and he distanced his two hands from his armpits, and placed his right thigh over his left thigh, and said: “Place (them) like this.” Wahb (the narrator) raised his index finger and made a knot with the middle finger. Muhammad bin Yahya also pointed with the index finger, made a circle with the middle finger and thumb, and made a knot with the middle finger.
