عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَا مِنْ قَوْمٍ جَلَسُوا مَجْلِسًا لَمْ يَذْكُرُوا اللَّهَ فِيهِ إِلَّا رَأَوْهُ حَسْرَةً يَوْمَ الْقِيَامَةِ
It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: In any gathering where people do not remember Allah Almighty, they will consider that gathering a cause of regret for themselves on the Day of Resurrection.
