But he who had knowledge of the Book, said: 'I will bring it to you before your glance comes back to you' And when he saw it set before him, he (Solomon) said: 'This is a favor from my Lord that He might test me whether I am thankful or ungrateful. Whosoever gives thanks gives thanks only for his (own soul's) good, but he who is ungrateful, truly my Lord is Rich and Generous'
