حَدَّثَنَا مُحَمَّدُ بْنُ حُمَيْدٍ الرَّازِيُّ قَالَ: حَدَّثَنَا جَرِيرٌ، عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ، عَنِ الصَّلتِ بْنِ عَبْدِ اللَّهِ قَالَ: كَانَ ابْنُ عَبَّاسٍ، يَتَخَتَّمُ فِي يَمِينِهِ وَلَا إِخَالُهُ إِلَّا قَالَ: «كَانَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَتَخَتَّمُ فِي يَمِينِهِ»
Salit bin Abdullah bin Naufal narrates that Sayyiduna Ibn Abbas (may Allah be pleased with them) used to wear a ring on his right hand, and I think he said that the Messenger of Allah (peace and blessings be upon him) also used to wear a ring on his right hand.
