The Expiation of Assembly - Kaffaratul-Majlis

سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ، أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ أَنْتَ، أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ

Subḥānaka llāhumma wa bi-ḥamdika, ashhadu an lā ilāha illā anta, astaghfiruka wa atūbu ilayk

How perfect You are O Allah, and I praise You. I bear witness that None has the right to be worshipped except You. I seek Your forgiveness and turn to You in repentance.
