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 some Gods who protect them from Us? Neither can they save themselves nor save their friends from Us. 43 Nay, We gave the good things of this life to these men and their fathers until the period grew long for them; See they not that We gradually reduce the land (in their control) from its outlying borders? Is it then they who will win? 44 Say, "I do but warn you according to revelation": But the deaf will not hear the call, (even) when they are warned! 45 But if just a breath of your Lord's punishment were to touch them, they would say: 'Woe for us, we were harmdoers' 46 But We shall set up just balance-scales on Resurrection Day, and no human being shall be wronged in the least: for though there be [in him but] the weight of a mustard-seed [of good or evil,] We shall bring it forth; and none can take count as We do! 47 Surely We had granted to Moses and Aaron the Criterion (between right and wrong), and Light and Admonition for the good of the God-fearing, 48 (For) those who fear their Lord in secret and they are fearful of the hour. 49 This is a blessed Reminder that we have revealed: Will ye then reject it? 50
