An-Naml - 27:44

قِيلَ لَهَا ادْخُلِي الصَّرْحَ فَلَمَّا رَأَتْهُ حَسِبَتْهُ لُجَّةً وَكَشَفَتْ عَن سَاقَيْهَا قَالَ إِنَّهُ صَرْحٌ مُّمَرَّدٌ مِّن قَوَارِيرَ قَالَتْ رَبِّ إِنِّي ظَلَمْتُ نَفْسِي وَأَسْلَمْتُ مَعَ سُلَيْمَانَ لِلَّهِ رَبِّ الْعَالَمِينَ
[27:44]
It was said to her: Enter the palace; but when she saw it she deemed it to be a great expanse of water, and bared her legs. He said: Surely it is a palace made smooth with glass. She said: My Lord! surely I have been unjust to myself, and I submit with Sulaiman to Allah, the Lord of the worlds.
She was asked to enter the lofty Palace: but when she saw it, she thought it was a lake of water, and she (tucked up her skirts), uncovering her legs. He said: "This is but a palace paved smooth with slabs of glass." She said: "O my Lord! I have indeed wronged my soul: I do (now) submit (in Islam), with Solomon, to the Lord of the Worlds."
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.
