Say: Who guards you by night and by day from the Beneficent Allah? Nay, they turn aside at the mention of their Lord. 42 Or have they gods who can shield them from Us? They cannot help themselves nor can they be defended from Us. 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 (Muhammad), tell them, "I am warning you by revelation alone." The deaf do not hear any 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 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 And We had already given Moses and Aaron the criterion and a light and a reminder for the righteous 48 Those who fear their Lord in secret and who dread the Hour (of doom). 49 This is a blessed remembrance, sent down by Us; so do you deny it? 50
