Tell them, (O Muhammad): "Who protects you, during the night or the day from the Most Compassionate Lord?" And yet they turn away from the Admonition 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 have allowed these [sinners] - as [We allowed] their forebears - to enjoy the good things of life for a great length of time: but then - have they never yet seen how We visit the earth [with Our punishment,] gradually depriving it of all that is best thereon? Can they, then, [hope to] be the winners? 44 Say: "I am warning you by God's command." But the deaf do not hear the call when they are warned. 45 But if just a breath of your Lord's punishment were to touch them, they would say: 'Woe for us, we were harmdoers' 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 And We had already given Moses and Aaron the criterion and a light and a reminder for the righteous 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 This (Quran) which We have revealed is a blessed reminder. Will you then deny it? 50
