Say thou: who guardeth you by night and by day from the Compassionate? Yet from the remembrance of their Lord they avert themselves! 42 Or do they have gods to defend them other than Us? They are unable [even] to help themselves, nor can they be protected from Us. 43 Aye! We let these people and their fathers enjoy until there grew long upon them the life. Behold they not that We come unto the land diminishing it by the borders thereof? Shall they then be the victors? 44 Say: I warn you only by revelation; and the deaf do not hear the call whenever they are warned. 45 If but a breath of thy Lord's chastisement touched them, they would surely say, 'Alas for us! We were evildoers.' 46 And We shall set up the just balances for the Resurrection Day, so that not one soul shall be wronged anything; even if it be the weight of one grain of mustard-seed We shall produce it, and sufficient are We for reckoners. 47 In the past We granted to Moses and Aaron the criterion (for judgment), and a Light and a Message for those who would do right,- 48 those who fear their Lord in the unseen, also dread the Hour of Judgement. 49 This is a blessed reminder that We have revealed to you. Will you then reject it? 50
