Say, "Who can protect you at night or by day from the Most Merciful?" But they are, from the remembrance of their Lord, turning away. 42 Or do they have lords of their own besides Us who can defend them? But they are not able to help themselves, nor can they find protection against Us. 43 Nay, We gave provision to these and their fathers until life was prolonged to them. Do they not then see that We are visiting the land, curtailing it of its sides? Shall they then prevail? 44 Say thou: I only warn you by the revelation; and the deaf hearken not unto the call when they are warned. 45 And yet, if but a breath of thy Sustainer's chastisement touches them, they are sure to cry, "Oh, woe unto us! Verily, 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 We gave Moses and Aaron the criterion of right and wrong and a light and reminder for the righteous, 48 These who fear their Lord unseen, and who are of the Hour fearful. 49 And this is a blessed Reminder (the Quran) which We have sent down, will you then (dare to) deny it? 50
