5ـ أَبُو عَلِيٍّ الأشْعَرِيُّ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ حُسَيْنِ بْنِ زَيْدٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وآلِه) مَا مِنْ قَوْمٍ اجْتَمَعُوا فِي مَجْلِسٍ فَلَمْ يَذْكُرُوا اسْمَ الله عَزَّ وَجَلَّ وَلَمْ يُصَلُّوا عَلَى نَبِيِّهِمْ إِلا كَانَ ذَلِكَ الْمَجْلِسُ حَسْرَةً وَوَبَالاً عَلَيْهِمْ.
5. Abu Ali al-Ash’ari has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from Husayn ibn Zayd from Abu ‘Abdillah (a.s.) who has said the following: “The Messenger of Allah has said, ‘If a people gather together in a place and do not speak of Allah, the Most Majestic, the Most Holy, and do not ask from Allah favors al-Salat for His Holy Prophet, that gathering will become a regret and a loss for them (on the Day of Judgment).’”
