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 Or have they gods to defend them, other than Us? Indeed, they are unable to help themselves, neither shall they be guarded in safety from Us. 43 Yet We bestowed the good things [of life] upon their fathers for a great length of time. But do they not see how We are shrinking their borders? Is it they who will prevail? 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 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 who fear their unseen Lord and are anxious about the Day of Judgment. 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
