It is narrated from Sulaiman bin Amr bin Ahwas Azdi, who says: My mother told me that she saw the Messenger of Allah, peace and blessings be upon him, stoning the Jamrah of Aqabah. After that, he moved forward and a woman came to him carrying her child and said: O Messenger of Allah! My son is insane, please pray to Allah Almighty for him. The Prophet, peace and blessings be upon him, said to her: Bring water. She brought water in a stone vessel, and the Prophet, peace and blessings be upon him, put his saliva into it and washed his face over the vessel, so that the water dripped down into it. Then the Prophet, peace and blessings be upon him, recited a supplication over the vessel and said: Go, bathe the child with this water and pray to Allah Almighty for healing. I said to her: Give me a little of this water so that I may give it to my son to drink. Then I took a little of the water with my finger and applied it to my son's lips. As a result, he became the most virtuous of all. After that, I asked the woman about her son, how he was. She told me that he had become completely well.
