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 Can their gods protect them against Us? Their gods have no power even to help themselves, nor are they safe from Our retribution. 43 But in fact We have given these (disbelievers) and their fathers a benefit to the extent that life became long for them; so do they not see that We are reducing the land from its borders? So will these be victorious? 44 Say, "I only warn you by revelation." But the deaf do not hear the call when they are warned. 45 And if a blast of the chastisement of your Lord were to touch them, they will certainly say: O woe to us! surely we were unjust. 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 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 which We have revealed; will you then deny it? 50
