وَ رَوَى مُحَمَّدُ بْنُ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: «تَجِبُ اَلْجُمُعَةُ عَلَى سَبْعَةِ نَفَرٍ مِنَ اَلْمُؤْمِنِينَ وَ لاَ تَجِبُ عَلَى أَقَلَّ مِنْهُمُ اَلْإِمَامُ وَ قَاضِيهِ وَ مُدَّعِيَا حَقٍّ وَ شَاهِدَانِ وَ اَلَّذِي يَضْرِبُ اَلْحُدُودَ بَيْنَ يَدَيِ اَلْإِمَامِ.
Muhammad ibn Muslim narrated from Imam Muhammad ibn Ali Al-Baqir (a.s) who said: "The Jumu’ah prayer (Salat al-Jumu'ah) is obligatory upon seven believers: the Imam, his judge, one who claims a right, two witnesses, and the one who executes punishments in front of the Imam. It is not obligatory for fewer than these."
