Say thou: who guardeth you by night and by day from the Compassionate? Yet from the remembrance of their Lord they avert themselves! 42 Or have they gods that can guard them from Us? They have no power to aid themselves, nor can they be defended from Us. 43 Nay, We generously provided them and their fathers, and they enjoyed Our provision for long. Do they not see that We are now advancing into their territory, diminishing it from different sides? Is it they, then, who will triumph?" 44 Say: 'I warn you only by the Revelation'; but they that are deaf do not hear the call when they are warned. 45 But if just a breath of your Lord's punishment were to touch them, they would say: 'Woe for us, we were harmdoers' 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 In the past We granted to Moses and Aaron the criterion (for judgment), and a Light and a Message for those who would do right,- 48 These who fear their Lord unseen, and who are of the Hour fearful. 49 And this is an admonition blest, which We have sent down! will ye then be the rejectors thereof? 50
