An-Naml 27:44

It was said to her, “Enter the palace.” But when she saw it, she thought it was a body of water[12], so she uncovered her calves. He said, “This is a palace paved with crystal.” She said, “My Lord, I have wronged myself, and now I submit along with Solomon to Allah, the Lord of the worlds.”

[12] The floor of the palace was transparent, under which was flowing water.

She was told, "Enter the palace." But when she saw it, she thought it was a body of water[1077] and uncovered her shins [to wade through]. He said, "Indeed, it is a palace [whose floor is] made smooth with glass." She said, "My Lord, indeed I have wronged myself, and I submit with Solomon to Allāh, Lord of the worlds."

[1077] The floor was transparent, and beneath it was flowing water.

44. It was said to her: "Enter As-Sarh" (a glass surface with water underneath it or a palace): but when she saw it, she thought it was a pool, and she (tucked up her clothes) uncovering her legs. (Sulaimân (Solomon)) said: "Verily, it is a Sarh (a glass surface with water underneath it or a palace)." She said: "My Lord! Verily, I have wronged myself, and I submit [in Islâm, together with Sulaimân (Solomon)] to Allâh, the Lord of the ‘Âlamîn (mankind, jinn and all that exists)."

It was said unto her: Enter the hall. And when she saw it she deemed it a pool and bared her legs. (Solomon) said: Lo! it is a hall, made smooth, of glass. She said: My Lord! Lo! I have wronged myself, and I surrender with Solomon unto Allah, the Lord of the Worlds.
