Hazrat Sa’ib bin Yazid (may Allah be pleased with him) said that my maternal aunt took me to the service of the Noble Prophet (peace and blessings be upon him) and said,“O Messenger of Allah! My nephew is ill.”The Prophet (peace and blessings be upon him) passed his hand over my head and prayed for blessings for me. Then the Prophet (peace and blessings be upon him) performed ablution, and I drank the leftover water from his ablution. Then I stood behind his back and saw the Seal of Prophethood between his shoulders, which was like the knob of a bedstead (or like a pigeon’s egg). (The leftover water from ablution was pure, that is why it was drunk. Therefore, those who say that used ablution water is impure are completely wrong.)
