Mukhtasar Bukhari

Saidna Sa’ib bin Yazid (may Allah be pleased with him) says that my maternal aunt took me to the Prophet Muhammad (peace and blessings be upon him) and said, "O Messenger of Allah! The son of my sister (this boy) is ill." So the Prophet (peace and blessings be upon him) placed his hand on my head and prayed for blessings for me. Then the Prophet (peace and blessings be upon him) performed ablution, and I drank the water that remained from his ablution. Then I stood behind the Prophet (peace and blessings be upon him) and I saw the Seal of Prophethood, which was between his two shoulders and was like the knob of a canopy.
