What is the interpretation of the verse: "Said he who had knowledge from the Scripture, 'I will bring it to you before your glance returns to you.' And when he saw it placed before him, he said, 'This is from the favor of my Lord to test me whether I will be grateful or ungrateful. And whoever is grateful - his gratitude is only for himself; and whoever is ungrateful - then indeed my Lord is Free of need and Generous'" (Quran 27:40); and who is the one with knowledge, is he from the jinn or humans, and what is his name?

When the Queen of Sheba learned of Solomon's (peace be upon him) warning, she decided to come to him. So Solomon asked who could bring her throne before her arrival. An ifrit from among the jinn offered to bring it before Solomon could rise from his seat, but Solomon desired something faster. Then a righteous man, who was said to be Asif ibn Barkhiya and knew the Greatest Name of Allah, said: "I will bring it to you before your glance returns to you." When Solomon saw the throne before him, he said: "This is from the favor of my Lord to test me whether I will be grateful or ungrateful."
