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 Or have they gods that can guard them from Us? They have no power to aid themselves, nor can they be defended from Us. 43 Nay, but Ourselves gave these and their fathers enjoyment of days, until their life had lasted long while upon them. What, do they not see how We come to the land, diminishing it in its extremities? Or are they the victors? 44 (Muhammad), tell them, "I am warning you by revelation alone." The deaf do not hear any call when they are warned. 45 And if a whiff of your Lord’s punishment were to touch them, they would certainly say, “Woe to us – we were indeed unjust!” 46 And We shall set up the just balances for the Resurrection Day, so that not one soul shall be wronged anything; even if it be the weight of one grain of mustard-seed We shall produce it, and sufficient are We for reckoners. 47 And certainly We gave to Musa and Haroun the Furqan and a light and a reminder for those who would guard (against evil). 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 This is a blessed Remembrance which We have sent down. Do you disbelieve it? 50
