Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: Shall I not show you how the Messenger of Allah (peace and blessings be upon him) used to perform ablution? So he called for a vessel of water. He took a handful of water, rinsed his mouth and put water into his nose; then he took another handful, gathered it in both hands and washed his face; then he took another handful and washed his right hand; then he took one more handful and washed his left hand; then he took a fistful of water, lowered his hand and wiped his head and ears with it; then he took one more handful and sprinkled it over his foot while it had a sandal on, and likewise the left foot, and he wiped the undersides of the sandals. Then he said: This is how (the Messenger of Allah (peace and blessings be upon him) used to perform ablution).
