My maternal aunt took me to the Messenger of Allah ﷺ and said, "Messenger of Allah, my nephew is ill."He wiped my head and prayed for blessing upon me, then he performed ablution, and I drank from the water of his ablution. Then I stood behind his back and looked at the Seal of Prophethood between his shoulders, resembling the Zirr of a bridal canopy.
ذهبت بي خالتي إلى رسول الله ﷺ فقالت: يا رسول الله، إن ابن أختي وجع فمسح رأسي، ودعا لي بالبركة، ثم توضأ فشربت من وضوئه ثم قمت خلف ظهره فنظرت إلى خاتمه بين كتفيه مثل زر الحجلة.
Bukhari narrated it in "Manaqib" (3541) and Muslim in "Fadail" (111:2345), both through the route of Hatim (that is, Ibn Ismail), from Jad bin Abdul-Rahman, who said, "I heard Saaib bin Yazid say," then he mentioned it.Jad bin Abdul-Rahman is also said to be Juayd bin Abdul-Rahman.His saying, "the button of the hijla," means "its egg," as Tirmidhi said (3642).
