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 Do they have other deities who can defend them against Us? They cannot even help themselves, neither can they be aided against 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 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 set a just balance for the Day of Resurrection so that no soul is wronged in aught. Though it be of the weight of a grain of mustard seed, We bring it. And We suffice for reckoners. 47 And We verily gave Moses and Aaron the Criterion (of right and wrong) and a light and a Reminder for those who keep from evil, 48 for those who fear their Lord without seeing Him and dread the Hour (of Reckoning). 49 And this is a blessed Message which We have sent down: will ye then reject it? 50
