Say: Who guardeth you in the night or in the day from the Beneficent? Nay, but they turn away from mention of their Lord! 42 Do they have any gods who would protect them against Us? They have no power even to help themselves; nor do they enjoy Our support. 43 Nay, but Ourselves gave these and their fathers enjoyment of days, until their life had lasted long while upon them. What, do they not see how We come to the land, diminishing it in its extremities? Or are they the victors? 44 Say: I warn you only by revelation; and the deaf do not hear the call whenever they are warned. 45 If a blast of the torment of your Lord strikes them, they will say, "Woe to us! We have been unjust people." 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 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 This is a Blessed Admonition that We have revealed. Are you, then, going to reject it? 50
