أَسْتَغْفِرُ اللَّهَ الَّذِي لَا إِلَٰهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ وَأَتُوبُ إِلَيْهِ
Astaghfirullaha-lladhi la ilaha illa huwal-Hayyul-Qayyumu wa atubu ilayh
Je demande pardon à Allah, il n'y a pas de divinité sauf Lui, le Vivant, l'Immuable, et je me repens vers Lui.
Recite for deep repentance and forgiveness of major sins
The Prophet (PBUH) said: 'Whoever says this, his sins will be forgiven even if they are as much as the foam of the sea.'
