Saaib bin Yazid reported,

My maternal aunt took me to the Messenger of Allah ﷺ and said, "Messenger of Allah, my sister's son is in pain."He wiped my head and prayed for blessing upon me, then 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, which was like the Zirr of a bridal canopy.

Muslim 6087

و حدثنا قتيبة بن سعيد ومحمد بن عباد قالا حدثنا حاتم وهو ابن إسمعيل عن الجعد بن عبد الرحمن قال سمعت

السائب بن يزيد يقول

ا 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
