وَإِذۡ تَأَذَّنَ رَبُّكُمۡ لَئِن شَكَرۡتُمۡ لَأَزِيدَنَّكُمۡۖ وَلَئِن كَفَرۡتُمۡ إِنَّ عَذَابِي لَشَدِيدٞ ٧
Wa idh taʾadhdhana rabbukum laʾin shakartum laʾazīdannakum, wa laʾin kafartum inna ʿadhābī lashadīd.
And [remember] when your Lord proclaimed, 'If you are grateful, I will surely increase you [in favor]; but if you deny, indeed, My punishment is severe.'"
