Musnad Ahmad

Abu Abdul Malik says that in the Fajr prayer, Abdu Khair (may Allah have mercy on him) used to lead us. One day, we had the opportunity to offer the Fajr prayer behind Sayyiduna Ali (may Allah be pleased with him). After completing the prayer and saying salam, when he stood up, we also stood up, until he walked into the courtyard of the mosque and sat down, leaning against the wall. Then he raised his head and said to his servant: Qanbar! Bring a bucket and a basin. Then he said: Pour water. He started pouring water, so first he (Ali) washed his palm three times, then put his right hand into the vessel and took out water, rinsed his mouth, and put water into his nose three times. Then he put both hands in, took out water, and washed his face three times. Then he put his right hand in, took out water, and washed his right hand three times, then washed his left hand three times, and said: This is the ablution of the Prophet (peace and blessings be upon him).
