Yahya bin Musa Khat يحيى بن موسى خت · The Book on Purification

"1 saw the Prophet rinse his mouth and sniff water in his nose using one hand, he did that thrice,"

the Prophet would go through his beard."

Ibn Abbas was asked ahout Tayammum. He said: "When Allah mentioned Wudu in His Book, He said: "So wash your faces and your hands (forearms) up to the elbows." And He said about Tayammum: "And rub therewith your faces and hands" And He said: "And the male thief and the female thief; cut off their hands." So the Sunnah for cutting is the two hands. So it is only the face and the hands, meaning, Tayammum."
