Say: "Who could protect you, by night or by day, from the Most Gracious?" And yet, from a remembrance of their Sustainer do they stubbornly turn away! 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 Yet We bestowed the good things [of life] upon their fathers for a great length of time. But do they not see how We are shrinking their borders? Is it they who will prevail? 44 Say thou: I only warn you by the revelation; and the deaf hearken not unto the call when they are warned. 45 If a blast of the torment of your Lord strikes them, they will say, "Woe to us! We have been unjust people." 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 We verily gave Moses and Aaron the Criterion (of right and wrong) and a light and a Reminder for those who keep from evil, 48 such as fear God in the Unseen, trembling because of the Hour. 49 This is a blessed reminder that We have revealed to you. Will you then reject it? 50
