Tell them, (O Muhammad): "Who protects you, during the night or the day from the Most Compassionate Lord?" And yet they turn away from the Admonition of their Lord. 42 Or do they have lords of their own besides Us who can defend them? But they are not able to help themselves, nor can they find protection against 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 [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 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 We had already given Moses and Aaron the criterion and a light and a reminder for the righteous 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
