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 performed ablution, and I drank from his ablution water. Then I stood behind him and looked at the Seal of Prophethood between his shoulders, like the Zirr of a bridal canopy.
ذهبت بي خالتي إلى رسول الله ﷺ فقالت: يا رسول الله إن ابن أخني وجع، فمسح رأسي، ودعا لي بالبركة، ثم توضأ فشربت من وضونه، ثم قمت خلف ظهره، فنظرت إلى خاتم النبوة بين كتفيه، مثل زر الحجلة.
Bukhari narrated it in the Book of Virtues (3541), and Muslim in the Book of Virtues (2345), both from the hadith of Hatim bin Ismail, from Jad bin Abdul-Rahman, from Saaib bin Yazid, who mentioned it. The wording given is that of Muslim, and Bukhari's wording is similar.
