Surah An-Nisa 4:147

مَّا يَفْعَلُ ٱللَّهُ بِعَذَابِكُمْ إِن شَكَرْتُمْ وَءَامَنتُمْ ۚ وَكَانَ ٱللَّهُ شَاكِرًا عَلِيمًا

What would Allāh do with [i.e., gain from] your punishment if you are grateful and believe? And ever is Allāh Appreciative and Knowing.

Translation: Saheeh International

Tafsir

Why would God chastise you if you are thankful of His favours and believe in Him? the interrogative is meant as a denial in other words He would not punish you. God is ever Thankful of the deeds of believers rewarding them Knowing of His creation.
