“Abu Ja‘far (a.s.), once said to us, ‘Should I demonstrate for you how the Messenger of Allah would take Wudu’?’ We replied, ‘Yes, please do so.’ He (the Imam) then asked for a bowl with a quantity of water in it. He (the Imam) placed it in front of him and uncovered both his forearms. He (the Imam) then immersed the palm of his right hand in the water, saying, ‘This is when the palm is clean and free of Najis (unclean) substances. He (the Imam) then filled the palm of his hand, placed on his forehead, saying ‘In the name of Allah’, allowed it to flow over the sides of his beard. He (the Imam) then passed his hand over his face and the apparent parts of his forehead only once. He (the Imam) then immersed his left hand in the water, filled his palm and placed it over his right elbow. He (the Imam) passed his palm over his forearm until water flowed toward the ends of his fingers. He (the Imam) then filled the palm of his right hand, placed it over his left elbow and passed it over his left forearm until water flowed over the ends of his fingers. He (the Imam) then wiped the front portion of his head and the back of his feet with whatever water was left in his left and right hands. Abu Ja‘far (a.s.), said, ‘Allah is odd. He loves odd numbers. Three handfuls of water is sufficient for Wudu’. One handful is for the face, one for the right forearm and one for the left forearm. With moisture in your right hand, wipe the front portion of your head, and with the remaining moisture on it wipe the back of your right foot and with the moisture in your left hand wipe the back of your left foot.’ Zurarah has said that Abu Ja‘far (a.s.), said, ‘Once a man asked ‘Amir al-Mu’minin about the Wudu’ of the Messenger of Allah and he (’Amir al-Mu’minin) demonstrated like this.’”
