As-Sa'ib b. Yazid reported: My mother's sister took me to Messenger of Allah ﷺ and said: Allah's Messenger, here is the son of my sister and he is ailing. He touched my head and invoked blessings upon me. He then performed ablution and I drank the water left from his ablution;
then I stood behind him and I saw the seal between his shoulders.

وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، وَمُحَمَّدُ بْنُ عَبَّادٍ، قَالاَ حَدَّثَنَا حَاتِمٌ، - وَهُوَ ابْنُ إِسْمَاعِيلَ
- عَنِ الْجَعْدِ بْنِ عَبْدِ الرَّحْمَنِ، قَالَ سَمِعْتُ السَّائِبَ بْنَ يَزِيدَ، 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 ثُمَّ قُمْتُ خَلْفَ ظَهْرِهِ فَنَظَرْتُ إِلَى خَاتِمِهِ
بَيْنَ كَتِفَيْهِ مِثْلَ زِرِّ الْحَجَلَةِ .
