سُبْحَانَ اللَّهِ وَبِحَمْدِهِ، أَسْتَغْفِرُ اللَّهَ وَأَتُوبُ إِلَيْهِ
Subhanallahi wa bihamdihi, astaghfirullaha wa atubu ilayh
アッラーに栄光あれ、彼に賞賛あれ。私はアッラーに許しを求め、彼に悔い改めます。
Recite frequently or after gatherings
The Prophet (PBUH) would say this when getting up from a gathering, and Aisha (RA) noted he said it often after Surah An-Nasr was revealed.
