أَسْتَغْفِرُ اللهَ الَّذِي لاَ إِلَهَ إلاَّ هُوَ الحَيُّ القَيّوُمُ وأَتُوبُ إِلَيهِ

Astaghfirullaah alladhee laa ilaaha illaa huwal hayyul qayyoomu wa atoobu ilayhi

I seek the forgiveness of Allah the Mighty, Whom there is none worthy of worship except Him, the Living, the Eternal, and I repent to Him, Allah will forgive him even if he has deserted the army’s ranks.

Abu Dawud: 1517

ذَٰلِكُمُ اللَّهُ رَبِّي عَلَيْهِ تَوَكَّلْتُ وَإِلَيْهِ أُنِيبُ

Dhalikumu Allahu rabbee alayhi tawakkaltu wa-ilayhi uneeb

(And say O Muhammad SAW to these polytheists:) Such is Allah, my Lord in Whom I put my trust, and to Him I turn in all of my affairs and in repentance.

Surah Ash-Shuraa – 42:10
