Say: "Who can keep you safe by night and by day from (the Wrath of) (Allah) Most Gracious?" Yet they turn away from the mention of their Lord. 42 Or, have they gods who can defend them against Us? They shall not be able to assist themselves, nor shall they be defended from Us. 43 Nay, We have allowed these [sinners] - as [We allowed] their forebears - to enjoy the good things of life for a great length of time: but then - have they never yet seen how We visit the earth [with Our punishment,] gradually depriving it of all that is best thereon? Can they, then, [hope to] be the winners? 44 Tell them: "I only warn you by the Revelation." But the deaf do not hear the cry when they are warned. 45 And if a breath of the torment of thy Lord were to touch them, they will say: woe unto us! we have been wrong-doers. 46 But We shall set up just balance-scales on Resurrection Day, and no human being shall be wronged in the least: for though there be [in him but] the weight of a mustard-seed [of good or evil,] We shall bring it forth; and none can take count as We do! 47 Surely We had granted to Moses and Aaron the Criterion (between right and wrong), and Light and Admonition for the good of the God-fearing, 48 Those who fear their Lord in their most secret thoughts, and who hold the Hour (of Judgment) in awe. 49 This is a blessed Remembrance which We have sent down. Do you disbelieve it? 50
