Say thou: who guardeth you by night and by day from the Compassionate? Yet from the remembrance of their Lord they avert themselves! 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 Say: 'I warn you only by the Revelation' But the deaf hear nothing when they are warned. 45 If but a breath of thy Lord's chastisement touched them, they would surely say, 'Alas for us! We were evildoers.' 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 We gave Moses and Aaron the Criterion, and gave them a light and a Remembrance for the cautious: 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 And this is a blessed reminder that We have sent down. Will you then deny it? 50
