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 to defend them, other than Us? Indeed, they are unable to help themselves, neither shall they be guarded in safety from Us. 43 Nay, We gave the good things of this life to these men and their fathers until the period grew long for them; See they not that We gradually reduce the land (in their control) from its outlying borders? Is it then they who will win? 44 SAY [unto all men]: "I but warn you on the strength of divine revelation!" But the deaf [of heart] will not hearken to this call, however often 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 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 is a blessed remembrance, sent down by Us; so do you deny it? 50
