Say, "Who can protect you at night or by day from the Most Merciful?" But they are, from the remembrance of their Lord, turning away. 42 Have they gods who defend them beside Us? They are not able to succour themselves, and against Us they cannot be kept company with. 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, "I only warn you by revelation." But the deaf do not hear the call when 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 shall set up balances of justice on the Day of Resurrection, then none will be dealt with unjustly in anything. And if there be the weight of a mustard seed, We will bring it. And Sufficient are We as Reckoners. 47 And assuredly We vcuchsafed unto Musa and Harun the distinction and illumination and an admonition for the God-fearing. 48 for those who fear their Lord without seeing Him and dread the Hour (of Reckoning). 49 And this is a blessed Reminder which We have revealed; will you then deny it? 50
