‘Abdullah b. Zaid b. ‘Asim al-Mazini reported: He saw Allah’s Messenger (peace be upon him) perform the ablution. He rinsed his mouth then cleaned his nose, then washed his face three times, then washed his right hand thrice and then the other one, thrice. He then took fresh water and wiped his head and then washed his feet till he cleaned them.
