Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they turn away. 42 Or do they have lords of their own besides Us who can defend them? But they are not able to help themselves, nor can they find protection against 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, "I warn you only through the Revelation." But the deaf can hear nothing 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 shall set up the just balances for the Resurrection Day, so that not one soul shall be wronged anything; even if it be the weight of one grain of mustard-seed We shall produce it, and sufficient are We for reckoners. 47 We gave Moses and Aaron the Criterion, and gave them a light and a Remembrance for the cautious: 48 who stand in awe of their Sustainer although He is beyond the reach of human perception, and who tremble at the thought of the Last Hour. 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
