And one who had the knowledge of Scripture said, "I will bring it to thee in the twinkling of an eye." And when he saw it set before him, he said, "This is of the favour of my Lord, to try me whether I will be thankful or unthankful. And he who is thankful is thankful to his own behoof; and as for him who is unthankful - truly my Lord is self-sufficient, bounteous!"
