Say: "Who could protect you, by night or by day, from the Most Gracious?" And yet, from a remembrance of their Sustainer do they stubbornly turn away! 42 Or have they gods who can shield them from Us? They cannot help themselves nor can they be defended from Us. 43 But, [on the contrary], We have provided good things for these [disbelievers] and their fathers until life was prolonged for them. Then do they not see that We set upon the land, reducing it from its borders? So it is they who will overcome? 44 Say: 'I warn you only by the Revelation'; but they that are deaf do not hear the call when they are warned. 45 If a blast of the torment of your Lord strikes them, they will say, "Woe to us! We have been unjust people." 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 those who fear their Lord in the unseen, also dread the Hour of Judgement. 49 This is a blessed Remembrance which We have sent down. Do you disbelieve it? 50
