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 Can their gods protect them against Us? Their gods have no power even to help themselves, nor are they safe from Our retribution. 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 Say, "I do but warn you according to revelation": But the deaf will not hear the call, (even) when they are warned! 45 And if [as much as] a whiff of the punishment of your Lord should touch them, they would surely say, "O woe to us! Indeed, we have been wrongdoers." 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 who stand in awe of their Sustainer although He is beyond the reach of human perception, and who tremble at the thought of the Last Hour. 49 And this is an admonition blest, which We have sent down! will ye then be the rejectors thereof? 50
