It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) performed ablution. He (peace and blessings be upon him) took a handful of water, rinsed his mouth and sniffed water into his nose; then he took a handful and washed his face; then he took a handful and washed his right hand; then he took a handful and washed his left hand; then he took some water and wiped his head, and with his middle fingers he wiped the inner part of his ears and with his thumbs the outer part too; then he took a handful and washed his right foot; then he took a handful and washed his left foot.
