Allah aided Prophet Solomon with knowledge and with expertise of construction. Prophet Solomon invited the queen of Sheba, and those who worked for Prophet Solomon made a throne for the queen which was identical to her own throne. They also constructed a hall made of smooth glass. It was made so perfectly that when the queen saw it, she thought it was a pool of water. The queen was moved and she immediately realized that such perfection of work can only come with the help of Allah, and she embraced Tawheed.
(˹Then˺ Solomon said, “Disguise her throne for her so we may see whether she will recognize ˹it˺ or she will not be able to.”So when she arrived, it was said ˹to her˺, “Is your throne like this?” She replied, “It looks to be the same. We have ˹already˺ received knowledge ˹of Solomon’s prophethood˺1 before this ˹miracle˺,2 and have submitted ˹to Allah˺.”) (An-Naml 27:41-44).
