My aunt took me to Messenger of Allah ﷺ and said, "O Messenger of Allah 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.  

سَمِعْتُ السَّائِبَ يَقُولُ ذَهَبَتْ بِي خَالَتِي إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ ابْنَ أُخْتِي وَجِعٌ فَمَسَحَ رَأْسِي وَدَعَا لِي بِالْبَرَكَةِ ثُمَّ تَوَضَّأَ فَشَرِبْتُ مِنْ وَضُوئِهِ وَقُمْتُ خَلْفَ ظَهْرِهِ فَنَظَرْتُ إِلَى خَاتَمِ النُّبُوَّةِ بَيْنَ كَتِفَيْهِ مِثْلَ زِرِّ الْحَجَلَةِ
