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 can guard them from Us? They have no power to aid themselves, nor can they be defended 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 Tell them: "I only warn you by the Revelation." But the deaf do not hear the cry when they are warned. 45 And if a breath of the torment of thy Lord were to touch them, they will say: woe unto us! we have been wrong-doers. 46 And We place the scales of justice for the Day of Resurrection, so no soul will be treated unjustly at all. And if there is [even] the weight of a mustard seed, We will bring it forth. And sufficient are We as accountant. 47 We gave Moses and Aaron the Criterion, and a light and reminder for those who take heed for themselves, 48 Who are fearful of their Lord inwardly and dread the Hour. 49 And this is a blessed Message which We have sent down: will ye then reject it? 50
