Say: Who guards you by night and by day from the Beneficent Allah? Nay, they turn aside at the mention of their Lord. 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 Nay, We gave the good things of this life to these men and their fathers until the period grew long for them; See they not that We gradually reduce the land (in their control) from its outlying borders? Is it then they who will win? 44 Say, "I warn you only through the Revelation." But the deaf can hear nothing 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 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 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 This is a blessed reminder that We have revealed to you. Will you then reject it? 50
