عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ أَبَانٍ عَنْ يَحْيَى بْنِ أَبِي الْعَلَاءِ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ كَانَ الْحَسَنُ وَ الْحُسَيْنُ ( عليهما السلام ) يَتَخَتَّمَانِ فِي يَسَارِهِمَا .
14. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from Ahmad ibn Muhammad from ibn abu Nasr from Aban from Yahya ibn abu al-‘Ala’ who has said the following: “Abu ‘Abd Allah عليه السلام, has said that al-Hassan and al-Husayn, ‘Alayhim al-Salam, wore the ring on their left hands.’”
