Arabic hadith text
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:" مَنْ جَلَسَ مَجْلِسًا فَكَثُرَ فِيهِ لَغَطُهُ فَقَالَ قَبْلَ أَنْ يَقُومَ: سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا أَنْتَ أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ إِلَّا غُفِرَ لَهُ مَا كَانَ فِي مَجْلِسِهِ ذَلِكَ ". رَوَاهُ التِّرْمِذِيّ وَالْبَيْهَقِيّ فِي الدَّعْوَات الْكَبِير
Translation

Abu Huraira reported God’s messenger as saying that if anyone sits in an assembly where there is much clamour* and says before getting up to leave, “Glory be to Thee, O God, and I begin with praise of Thee; I testify that there is no god but Thou; I ask Thy pardon and turn to Thee in repentance,” he will be forgiven for what took place in that assembly where he was. *Or, ‘wicked talk,’ or, 'meaningless talk'Tirmidhi and Baihaqi in [Kitab] ad-Da'awat al-kabir, transmitted it.
