(18) باب مَنْ ذَهَبَ بِالصَّبِيِّ الْمَرِيضِ لِيُدْعَى لَهُ
Narrated As-Sa'ib:
My aunt took me to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! My nephew is- ill." The Prophet (ﷺ) touched my head with his hand and invoked Allah to bless me. He then performed ablution and I drank of the remaining water of his ablution and then stood behind his back and saw "Khatam An- Nubuwwa" (The Seal of Prophethood) between his shoulders like a button of a tent.
