Ikrama عكرمة · The Book on Purification

"One of the wives of the Prophet performed Ghusl with a bowl. Allah's Messenger wanted to perform Wudu with it, so she said: 'O Messenger of Allah! Indeed I am ]unub.' So he said: 'Indeed, water does not become Junub.'"

"Water is for water' is only about the wet dream."

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."
