As-Sa'ib b. Yazid reported:
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 صلى الله عليه وسلم 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 .
My mother's sister took me to Allah's Messenger (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.
