2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ جَمِيلِ بْنِ دَرَّاجٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ وَزُرَارَةَ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) قَالَ تَجِبُ الْجُمُعَةُ عَلَى مَنْ كَانَ مِنْهَا عَلَى فَرْسَخَيْنِ.
2. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Um ay r from Jamil ibn Darraj from Muhammad ibn Muslim and Zurarah who have said the following: “Abu Ja‘far (a.s.), has said, ‘Friday Salah (prayer) is not obligatory upon those who are two farsakh (about six miles) away (from the location of the congregation).”’
