Say thou: who guardeth you by night and by day from the Compassionate? Yet from the remembrance of their Lord they avert themselves! 42 Have they gods who defend them beside Us? They are not able to succour themselves, and against Us they cannot be kept company with. 43 But, [on the contrary], We have provided good things for these [disbelievers] and their fathers until life was prolonged for them. Then do they not see that We set upon the land, reducing it from its borders? So it is they who will overcome? 44 Say: 'I warn you only by the Revelation' But the deaf hear nothing when they are warned. 45 And if a breath of thy Lord's punishment were to touch them, they assuredly would say: Alas for us! Lo! we were wrong-doers. 46 And We shall set balances of justice for the Day of Judgment; then no soul shall be wronged at all; and if it be but the weight of a grain of mustard-seed We shall bring it; and We suffice as Reckoners. 47 AND, INDEED, We vouchsafed unto Moses and Aaron [Our revelation as] the standard by which to discern the true from the false, and as a [guiding] light and a reminder for the God-conscious 48 those who fear Allah in the Unseen, tremble because of the Hour. 49 And this [Qur'an] is a blessed message which We have sent down. Then are you with it unacquainted? 50
