Say: "Who could protect you, by night or by day, from the Most Gracious?" And yet, from a remembrance of their Sustainer do they stubbornly turn away! 42 Do they have some Gods who protect them from Us? Neither can they save themselves nor save their friends 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 (O Muhammad, unto mankind): I warn you only by the Inspiration. But the deaf hear not the call when they are warned. 45 And if a breath of thy Lord's punishment were to touch them, they assuredly would say: Alas for us! Lo! we were 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 We gave Moses and Aaron the Criterion, and a light and reminder for those who take heed for themselves, 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 This is a blessed remembrance, sent down by Us; so do you deny it? 50
