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 We allowed them and their fathers time to enjoy till the very end of their lives. Do they not see Us advancing into the land, reducing its frontiers? Would they still prevail? 44 Tell them: "I only warn you by the Revelation." But the deaf do not hear the cry when 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 will set up a just balance on the day of resurrection, so no soul shall be dealt with unjustly in the least; and though there be the weight of a grain of mustard seed, (yet) will We bring it, and sufficient are We to take account. 47 And assuredly We vcuchsafed unto Musa and Harun the distinction and illumination and an admonition for the God-fearing. 48 These who fear their Lord unseen, and who are of the Hour fearful. 49 This (Quran) which We have revealed is a blessed reminder. Will you then deny it? 50
