Dua at the End of a Gathering

سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا أَنْتَ أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَPurity belongs to You. O Allah (SWT), with Your praises, I bear witness that there is non worthy of worship exceptYou. I seek forgiveness from You and I repent to You.(Tirmidhi)Source:Central Mosque
