Say, "Who can protect you at night or by day from the Most Merciful?" But they are, from the remembrance of their Lord, turning away. 42 Do they have some Gods who protect them from Us? Neither can they save themselves nor save their friends 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 Tell them: "I only warn you by the Revelation." But the deaf do not hear the cry 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 We shall set up scales of justice for the Day of Judgment, so that not a soul will be dealt with unjustly in the least, and if there be (no more than) the weight of a mustard seed, We will bring it (to account): and enough are We to take account. 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 Those who fear their Lord without seeing and who apprehend the Last Day. 49 And this is a blessed Message which We have sent down: will ye then reject it? 50
