عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ أَبَانٍ عَنْ يَحْيَى بْنِ أَبِي الْعَلَاءِ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) أَنَّهُ سَأَلَهُ عَنِ التَّخَتُّمِ فِي الْيَمِينِ وَ قُلْتُ إِنِّي رَأَيْتُ بَنِي هَاشِمٍ يَتَخَتَّمُونَ فِي أَيْمَانِهِمْ فَقَالَ كَانَ أَبِي يَتَخَتَّمُ فِي يَسَارِهِ وَ كَانَ أَفْضَلَهُمْ وَ أَفْقَهَهُمْ .
8. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from Ali ibn al-Hakam from Aban from Yahya ibn abu al-‘Ala’ who has said the following: “I once asked abu ‘Abd Allah , about wearing the ring on the right hand saying, ‘I have seen banu Hashim wearing rings on their right hands.’ He (the Imam) said, ‘My father would wear it on his left hand and he was the most excellent among them with more power of wisdom.’” (This is because of Taqiyah, according to al-Majlisy)
