30 – Humrān reported: “ʿUthmān asked for water with which to perform wudūʾ (ablution). He washed his palms three times, then rinsed his mouth, drew water into his nose and blew it out, washed his face three times, washed his right arm up to and including the elbow three times, then his left likewise, wiped his head, washed his right foot up to and including the ankles three times, and then the left in the same manner. He concluded, ‘I saw the Messenger of Allah ﷺ perform ablution in a way very similar to this wudūʾ of mine.’” Agreed upon. (1)

Glossary of hadith terms
– daʿā: here means “to request the water for wudūʾ.”
– wudūʾ: with an open wāw it refers to the water used for ablution; with a closed (damma) wāw it denotes the act itself.
– kafayhi (his two palms): dual of kaf, the inner hand together with the fingers. Feminine in Arabic; its plurals are kufūf and akuff. Its anatomical limit is the wrist joint. It is called kaf because a person uses it to ward off harm.
– tammaḍmaḍa: madhmadhah—placing water in the mouth; its complete form is to swish the water around and then spit it out or swallow it.
– wajhihi (his face): plural wujūh. Lexically it is what one confronts others with. Its legal limits in ablution are from the usual hairline to the bottom of the chin in length, and from ear to ear in width; this definition is taken from the language, for the Sharīʿah did not set a separate technical boundary.
– istan shaqa: the verb istan shaqa al-māʾ means to draw water into the nose and pull it inward.
