Ash-Shama'il Al-Muhammadiyah 96
Hammad ibn Salama said:
"I saw Ibn Abi Rafi' wearing a signet ring on his right hand, so I asked him about that and he said: 'I saw 'Abdu llah ibn Ja'far wearing a signet ring on his right hand', and 'Abdullah ibn Ja'far said:
'Allah’s Messenger (Allah bless him and give him peace) used to wear a signet ring on his right hand'.”
حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ ، قَالَ : حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ ، عَنْ حَمَّادِ بْنِ سَلَمَةَ ، قَالَ : رَأَيْتُ ابْنَ أَبِي رَافِعٍ يَتَخَتَّمُ فِي يَمِينِهِ فَسَأَلْتُهُ عَنْ ذَلِكَ , فَقَالَ : رَأَيْتُ عَبْدَ اللَّهِ بْنَ جَعْفَرٍ يَتَخَتَّمُ فِي يَمِينِهِ وَقَالَ عَبْدُ اللَّهِ بْنُ جَعْفَرٍ : 
" كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَتَخَتَّمُ فِي يَمِينِهِ " .
