Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they turn 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 Nay, but Ourselves gave these and their fathers enjoyment of days, until their life had lasted long while upon them. What, do they not see how We come to the land, diminishing it in its extremities? Or are they the victors? 44 Say: 'I warn you only by the Revelation'; but they that are deaf do not hear the call when they are warned. 45 Even if a whiff of the Lord's chastisement were to touch them they would surely say: "Ah woe, alas, we were surely sinful." 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 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 (For) those who fear their Lord in secret and they are fearful of the hour. 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
