Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they turn away. 42 Do they have some Gods who protect them from Us? Neither can they save themselves nor save their friends from Us. 43 We have been providing these men and their fathers with the means of enjoyment for a long time. Have they not ever considered that We populated the earth and then caused many of the inhabitants to pass away? Can they have any success (in their wickedness)? 44 Say (O Muhammad, unto mankind): I warn you only by the Inspiration. But the deaf hear not the call when they are warned. 45 If but a breath of thy Lord's chastisement touched them, they would surely say, 'Alas for us! We were evildoers.' 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, INDEED, We vouchsafed unto Moses and Aaron [Our revelation as] the standard by which to discern the true from the false, and as a [guiding] light and a reminder for the God-conscious 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 And this [Qur'an] is a blessed message which We have sent down. Then are you with it unacquainted? 50
