وَإِذۡ تَأَذَّنَ رَبُّكُمۡ لَئِن شَكَرۡتُمۡ لَأَزِيدَنَّكُمۡ ۖ وَلَئِن كَفَرۡتُمۡ إِنَّ عَذَابِى لَشَدِيدٌ
And remember! your Lord caused to be declared (publicly): "If ye are grateful, I will add more (favours) unto you; But if ye show ingratitude, truly My punishment is terrible indeed."<br/>
And when your Lord proclaimed, [when] He made it known that: "If you are thankful, for My graces, through affirmation of [My] Oneness and obedience [to Me], then assuredly I shall give you more; but if you are thankless, [if] you deny [the truth of] the grace, through disbelief and disobedience, then assuredly I shall chastise you - as is indicated by [His following words] - My chastisement is indeed severe" '.
