'Amr bin Yahya narrated that his father said to 'Abdullah bin Zaid who was the grandfather of 'Arm bin Yahya: "Can you show me how the Messenger of Allah used to perform ablution?' 'Abdullah binZaid said: "Yes." So he called for water, poured it over his hands and washed his hands twice. Then he rinsed his mouth and sniffed water up into his nostrils three times. Then he washed his face three times and his arms up to the elbows twice. Then he wiped his head with his hands, from front to back. He started at the front of his head, then went with them to the nape of his neck, then he brought them back, returning them to the place he started, then he washed his feet."
