Say: 'Who shall guard you by night and in the daytime from the All-merciful?' Nay, but from the Remembrance of their Lord they are turning away. 42 Or do they have gods to defend them other than Us? They are unable [even] to help themselves, nor can they be protected from Us. 43 Nay, but We gave these and their fathers ease until life grew long for them. See they not how we aim to the land, reducing it of its outlying parts? Can they then be the victors? 44 Say: 'I warn you only by the Revelation' But the deaf hear nothing when they are warned. 45 And if a blast of the chastisement of your Lord were to touch them, they will certainly say: O woe to us! surely we were unjust. 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 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 This is a blessed Remembrance which We have sent down. Do you disbelieve it? 50
