عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ مَا قَعَدَ قَوْمٌ مَقْعَدًا لَا يَذْكُرُونَ اللَّهَ عَزَّ وَجَلَّ وَيُصَلُّونَ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِلَّا كَانَ عَلَيْهِمْ حَسْرَةً يَوْمَ الْقِيَامَةِ وَإِنْ دَخَلُوا الْجَنَّةَ لِلثَّوَابِ
Sayyiduna Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Those people who sit in a gathering and neither remember Allah Almighty nor send blessings upon the Noble Prophet (peace and blessings be upon him), that gathering will be a cause of regret for them on the Day of Resurrection, even if they enter Paradise due to other deeds.
