Say: 'Who shall guard you by night and in the daytime from the All-merciful?' Nay, but from the Remembrance of their Lord they are turning away. 42 Do they have some Gods who protect them from Us? Neither can they save themselves nor save their friends from 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, 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 the Wrath of thy Lord do touch them, they will then say, "Woe to us! we did wrong indeed!" 46 We shall set up scales of justice on the Day of Resurrection, so that no soul can be in the least wronged. Actions as small as a grain of mustard seed shall be weighed. We are sufficient as a reckoner. 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 those who fear their Lord in the unseen, also dread the Hour of Judgement. 49 This is a blessed Remembrance which We have sent down. Do you disbelieve it? 50
