٤ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ عَبْدِ الله بْنِ الْمُغِيرَةِ عَنْ جَمِيلٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) قَالَ إِنَّ الله أَكْرَمَ بِالْجُمُعَةِ الْمُؤْمِنِينَ فَسَنَّهَا رَسُولُ الله (صلّى اللهُ عَلَيْهِ وَآلِه) بِشَارَةً لَهُمْ وَالْمُنَافِقِينَ تَوْبِيخاً لِلْمُنَافِقِينَ وَلاَ يَنْبَغِي تَرْكُهَا فَمَنْ تَرَكَهَا مُتَعَمِّداً فَلاَ صَلاَةَ لَهُ.
4. Ali ibn Ibrahim has narrated from his father from ‘Abd Allah ibn al-Mughirah from Jamil from Muhammad ibn Muslim who has said the following: “Abu Ja‘far , has said, ‘Allah has granted honor to the believers by means of sending (Surah (chapter) of al-Jumu‘ah). The Messenger of Allah established it a Sunnah (noble tradition) and good news for them. He sent al-Munafiqun to reprimand the hypocrites. It is not proper to omit it. Salah (prayer) of one who willfully omits it is not valid.’”
