As-Sa’ib ibn Yazid said: ‘My maternal aunt took me to the Prophet (Allah bless him and give him peace), and she said; “O Messenger of Allah, my sister's son is in pain!” He therefore stroked my head (Allah bless him and give him peace) and supplicated blessing for my sake. He performed the minor ritual ablution. I drank from his ablution water and stood behind his back, whereupon I observed the Seal between his shoulders, and lo and behold, it was like the button of the bridal canopy!”’
