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»
“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 Jafar wearing a signet ring on his right hand’, and Abdullah ibn Jafar said: ‘the Messenger of Allah (sallallahu alayhi wa sallam) used to wear a signet ring on his right hand’.’”
