Musannaf Ibn Abi Shaybah 1692 — How tayammum is performed

Al-Sha'bi said: In tayammum one strikes the ground once, for the face and also for both arms up to the elbows. Dawud described the method of tayammum thus: he struck both his hands on the ground once, then shook them off, then rubbed his two palms together, then wiped both hands over his face and then over both his arms up to the elbows.
