Say: 'Who will guard you, by night and by day from the Merciful' But no, they turn away from their Lord's remembrance. 42 Or have they gods that can guard them from Us? They have no power to aid themselves, nor can they be defended from Us. 43 But, [on the contrary], We have provided good things for these [disbelievers] and their fathers until life was prolonged for them. Then do they not see that We set upon the land, reducing it from its borders? So it is they who will overcome? 44 Say, "I do but warn you according to revelation": But the deaf will not hear the call, (even) 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 verily gave Moses and Aaron the Criterion (of right and wrong) and a light and a Reminder for those who keep from evil, 48 such as fear God in the Unseen, trembling because of the Hour. 49 And this is a blessed Reminder (the Quran) which We have sent down, will you then (dare to) deny it? 50
