Say: 'Who will guard you, by night and by day from the Merciful' But no, they turn away from their Lord's remembrance. 42 Do they [really think that they] have deities that could shield them from Us? Those [alleged deities] are not [even] able to succour themselves: hence, neither can they [who worship them hope to] be aided [by them] against Us. 43 Nay, We have allowed these [sinners] - as [We allowed] their forebears - to enjoy the good things of life for a great length of time: but then - have they never yet seen how We visit the earth [with Our punishment,] gradually depriving it of all that is best thereon? Can they, then, [hope to] be the winners? 44 Say (O Muhammad SAW): "I warn you only by the revelation (from Allah and not by the opinion of the religious scholars and others). But the deaf (who follow the religious scholars and others blindly) will not hear the call, (even) when they are warned [(i.e. one should follow only the Quran and the Sunnah (legal ways, orders, acts of worship, statements of Prophet Muhammad SAW, as the Companions of the Prophet SAW did)]. 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 We shall set up scales of justice for the Day of Judgment, so that not a soul will be dealt with unjustly in the least, and if there be (no more than) the weight of a mustard seed, We will bring it (to account): and enough are We to take account. 47 And certainly We gave to Musa and Haroun the Furqan and a light and a reminder for those who would guard (against evil). 48 Those who fear their Lord without seeing and who apprehend the Last Day. 49 And this is an admonition blest, which We have sent down! will ye then be the rejectors thereof? 50
