Say: Who guardeth you in the night or in the day from the Beneficent? Nay, but they turn away from mention of their Lord! 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 But in fact We have given these (disbelievers) and their fathers a benefit to the extent that life became long for them; so do they not see that We are reducing the land from its borders? So will these be victorious? 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 On the Day of Resurrection We shall set up just scales, so that no soul shall in the least be wronged, even though it be the weight of a grain of mustard seed We will bring it; We Suffice 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 Those who fear their Lord in secret and who dread the Hour (of doom). 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
