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 who can shield them from Us? They cannot help themselves nor can they be defended from Us. 43 Aye! We let these people and their fathers enjoy until there grew long upon them the life. Behold they not that We come unto the land diminishing it by the borders thereof? Shall they then be the victors? 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 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 We gave Moses and Aaron the Criterion, and a light and reminder for those who take heed for themselves, 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 And this [Qur'an] is a blessed message which We have sent down. Then are you with it unacquainted? 50
