عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ إِنَّ الْمَجَالِسَ ثَلَاثَةٌ سَالِمٌ وَغَانِمٌ وَشَاجِبٌ
Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Gatherings are of three types: one of safety, one of benefit, and one of idle and nonsensical talk.
