Say: 'Who shall guard you by night and in the daytime from the All-merciful?' Nay, but from the Remembrance of their Lord they are turning away. 42 Or have they gods to defend them, other than Us? Indeed, they are unable to help themselves, neither shall they be guarded in safety from Us. 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 (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 breath (minor calamity) of the Torment of your Lord touches them, they will surely cry: "Woe unto us! Indeed we have been Zalimun (polytheists and wrong-doers, etc.). 46 We shall maintain proper justice on the Day of Judgment. No soul will be wronged the least. For a deed even as small as a mustard seed one will duly be recompensed. We are efficient in maintaining the account. 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 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 This is a blessed Remembrance which We have sent down. Do you disbelieve it? 50
