[Machine] Narrated by Prophet Muhammad ﷺ : "Whoever sits in a gathering where there is idle talk, and before leaving, says: 'Subhanaka Allahumma wa bihamdika, ash-hadu an la ilaha illa Anta, astaghfiruka wa atubu ilayk' (Glory be to You, O Allah, and all praise is due to You. I testify that there is no deity worthy of worship except You. I seek Your forgiveness and repent to You),' Allah will forgive him for what was said in that gathering."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ جَلَسَ فِي مَجْلِسٍ كَثُرَ فِيهِ لَغَطُهُ فَقَالَ قَبْلَ أَنْ يَقُومَ سُبْحَانَكَ رَبَّنَا وَبِحَمْدِكَ لَا إِلَهَ إِلَّا أَنْتَ أَسْتَغْفِرُكَ ثُمَّ أَتُوبُ إِلَيْكَ إِلَّا غَفَرَ اللهُ لَهُ مَا كَانَ فِي مَجْلِسِهِ ذَلِكَ  

[Machine] The Prophet ﷺ used to say "Subhanak Allahumma rabbi wa bihamdik, la ilaha illa anta astaghfiruka wa atubu ilayk" whenever he would rise from a gathering. So, I asked him, "O Messenger of Allah, why do you often say these words when you rise?" He replied, "Whoever says these words when rising from a gathering, all his sins committed in that gathering will be forgiven."  

مَا كَانَ رَسُولُ اللَّهِ ﷺ يَقُومُ مِنْ مَجْلِسٍ إِلَّا قَالَ «سُبْحَانَكَ اللَّهُمَّ رَبِّي وَبِحَمْدِكَ لَا إِلَهَ إِلَّا أَنْتَ أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ» فَقُلْتُ لَهُ يَا رَسُولَ اللَّهِ مَا أَكْثَرَ مَا تَقُولُ هَؤُلَاءِ الْكَلِمَاتِ إِذَا قُمْتَ قَالَ «لَا يَقُولُهُنَّ مِنْ أَحَدٍ حِينَ يَقُومُ مِنْ مَجْلِسِهِ إِلَّا غُفِرَ لَهُ مَا كَانَ مِنْهُ فِي ذَلِكَ الْمَجْلِسِ»
