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 Do they have any gods who would protect them against Us? They have no power even to help themselves; nor do they enjoy Our support. 43 But in fact We have given these (disbelievers) and their fathers a benefit to the extent that life became long for them; so do they not see that We are reducing the land from its borders? So will these be victorious? 44 Say thou: I only warn you by the revelation; and the deaf hearken not unto the call when they are warned. 45 And if a breath of thy Lord's punishment were to touch them, they assuredly would say: Alas for us! Lo! we were wrong-doers. 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 In the past We granted to Moses and Aaron the criterion (for judgment), and a Light and a Message for those who would do right,- 48 for those who fear their Lord without seeing Him and dread the Hour (of Reckoning). 49 This is a blessed remembrance, sent down by Us; so do you deny it? 50
