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 do they have gods to defend them other than Us? They are unable [even] to help themselves, nor can they be protected 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 Say thou: I only warn you by the revelation; and the deaf hearken not unto the call when they are warned. 45 If but a breath of the Wrath of thy Lord do touch them, they will then say, "Woe to us! we did wrong indeed!" 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, INDEED, We vouchsafed unto Moses and Aaron [Our revelation as] the standard by which to discern the true from the false, and as a [guiding] light and a reminder for the God-conscious 48 (For) those who fear their Lord in secret and they are fearful of the hour. 49 This is a blessed remembrance, sent down by Us; so do you deny it? 50
