Say: Who guardeth you in the night or in the day from the Beneficent? Nay, but they turn away from mention of their Lord! 42 Do they have any gods who would protect them against Us? They have no power even to help themselves; nor do they enjoy Our support. 43 We gave days of enjoyment to them and their fathers until their life became long. Are they unable to see how We come to their land and reduce its borders. Or, is it they who are 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 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 We verily gave Moses and Aaron the Criterion (of right and wrong) and a light and a Reminder for those who keep from evil, 48 Those who fear their Lord in their most secret thoughts, and who hold the Hour (of Judgment) in awe. 49 And this [Qur'an] is a blessed message which We have sent down. Then are you with it unacquainted? 50
