abudawud:4227Naṣr b. ʿAlī from my father > ʿAbd al-ʿAzīz b. Abū Rawwād > Nāfiʿ > Ibn ʿUmar

The Prophet ﷺ used to wear the signet-ring on his left hand, and put its stone next the palm of his hand. Abu Dawud said: Ibn Ishaq and Usamah b. Zaid transmitted from Nafi': "On his right hand".  

أبو داود:٤٢٢٧حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ حَدَّثَنِي أَبِي حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي رَوَّادٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ

أَنَّ النَّبِيَّ ﷺ كَانَ يَتَخَتَّمُ فِي يَسَارِهِ وَكَانَ فَصُّهُ فِي بَاطِنِ كَفِّهِ  

قَالَ أَبُو دَاوُدَ قَالَ ابْنُ إِسْحَاقَ وَأُسَامَةَ يَعْنِي ابْنَ زَيْدٍ عَنْ نَافِعٍ بِإِسْنَادِهِ فِي يَمِينِهِ
