سَهْلُ بْنُ زِيَادٍ عَنْ بَعْضِ أَصْحَابِهِ عَنْ وَاصِلِ بْنِ سُلَيْمَانَ عَنْ عَبْدِ اللَّهِ بْنِ سِنَانٍ قَالَ ذَكَرْنَا خَاتَمَ رَسُولِ اللَّهِ ( صلى الله عليه وآله ) فَقَالَ تُحِبُّ أَنْ أُرِيَكَهُ فَقُلْتُ نَعَمْ فَدَعَا بِحُقٍّ مَخْتُومٍ فَفَتَحَهُ وَ أَخْرَجَهُ فِي قُطْنَةٍ فَإِذَا حَلْقَةُ فِضَّةٍ وَ فِيهِ فَصٌّ أَسْوَدُ عَلَيْهِ مَكْتُوبٌ سَطْرَانِ مُحَمَّدٌ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) قَالَ ثُمَّ قَالَ إِنَّ فَصَّ النَّبِيِّ ( صلى الله عليه وآله ) أَسْوَدُ .
7. Sahf ibn Ziyad has narrated from certain persons of his people from Wasil ibn Sulayman from ‘Abd Allah ibn Sinan who has said the following: “Once we mentioned the ring of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, and he (the Imam) said, ‘Will you like if I show you?’ I replied, ‘Yes, (I will be delighted to see it).’ He (the Imam) then asked for a sealed package and took from it a pack of cotton in which there was a ring of silver. It had a piece of black stone with two lines of writing that said, ‘Muhammad is the Messenger of Allah.’ He (the narrator) has said that he (the Imam) said, ‘The stone of the ring of the Holy Prophet is black.’”
