Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they turn away. 42 Can their gods protect them against Us? Their gods have no power even to help themselves, nor are they safe from Our retribution. 43 Yet We bestowed the good things [of life] upon their fathers for a great length of time. But do they not see how We are shrinking their borders? Is it they who will prevail? 44 Say, "I only warn you by revelation." But the deaf do not hear the call when they are warned. 45 And yet, if but a breath of thy Sustainer's chastisement touches them, they are sure to cry, "Oh, woe unto us! Verily, we were evildoers!" 46 We shall fix the scales of justice on the Day of Resurrection, so that none will be wronged in the least; and even if it were equal to a mustard seed in weight We shall take it (into account). We are sufficient for computation. 47 We gave Moses and Aaron the criterion of right and wrong and a light and reminder for the righteous, 48 Those who fear their Lord in secret and who dread the Hour (of doom). 49 And this is a blessed Message which We have sent down: will ye then reject it? 50
