عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ صَفْوَانَ رَفَعَهُ إِلَى أَبِي جَعْفَرٍ أَوْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ هَذَا مُحَمَّدٌ أُذِنَ لَهُمْ فِي التَّسْمِيَةِ بِهِ فَمَنْ أَذِنَ لَهُمْ فِي يس يَعْنِي التَّسْمِيَةَ وَ هُوَ اسْمُ النَّبِيِّ ( صلى الله عليه وآله ).

13. A number of our people have narrated from Ahmad ibn Khalid from Muhammad ibn ‘Isa from Safwan ibn in a marfu‘ manner who has said the following: “Abu Ja‘far, or abu ‘ Abd Allah, ‘Alayhi al-Salam, has stated this Hadith. ‘This is ‘Muhammad’ (the Messenger of Allah) who has given them permission to name themselves with his name. However, who has given them permission to name themselves ‘Yasin’ which is the name of the Holy Prophet, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause )?’”
