Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they turn away. 42 Or have they gods that shall defend them apart from Us? Why, they are not able to help themselves, nor 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 (Muhammad), tell them, "I am warning you by revelation alone." The deaf do not hear any call when they are warned. 45 Were only the slightest whiff from your Lord's punishment to touch them, they would cry out: "Woe to us; we were indeed wrong-doers." 46 We shall maintain proper justice on the Day of Judgment. No soul will be wronged the least. For a deed even as small as a mustard seed one will duly be recompensed. We are efficient in maintaining the account. 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 their most secret thoughts, and who hold the Hour (of Judgment) in awe. 49 This is a Blessed Admonition that We have revealed. Are you, then, going to reject it? 50
