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 We gave days of enjoyment to them and their fathers until their life became long. Are they unable to see how We come to their land and reduce its borders. Or, is it they who are the victors? 44 Say thou: I only warn you by the revelation; and the deaf hearken not unto the call when they are warned. 45 And yet, if but a breath of thy Sustainer's chastisement touches them, they are sure to cry, "Oh, woe unto us! Verily, we were evildoers!" 46 We shall set up just scales on the Day of Resurrection so that none will be wronged in the least. (We shall bring forth the acts of everyone), even if it be the weight of a grain of mustard seed. We shall suffice as Reckoners. 47 And assuredly We vcuchsafed unto Musa and Harun the distinction and illumination and an admonition for the God-fearing. 48 Those who fear their Lord in their most secret thoughts, and who hold the Hour (of Judgment) in awe. 49 And this is an admonition blest, which We have sent down! will ye then be the rejectors thereof? 50
