Ata bin Yasar says that once Sayyiduna Ibn Abbas (may Allah be pleased with them both) performed ablution; in it, he washed his face, took a handful of water and rinsed his mouth, put water into his nose, then took another handful of water and, joining the other hand with it, washed his face, then took a handful of water and washed his right hand, then took a handful of water and washed his left hand, wiped his head, then took a handful of water and poured it over his right foot and washed it, then took another handful of water and washed his left foot, then said that I have seen the Prophet (peace and blessings be upon him) doing it in this manner.
