Surah An-Naml (The Ants), Verse 44

قِیْلَ لَهَا ادْخُلِی الصَّرْحَ فَلَمَّا رَاَتْهُ حَسِبَتْهُ لُجَّةً وَّكَشَفَتْ عَنْ سَاقَیْهَا قَالَ اِنَّهٗ صَرْحٌ مُّمَرَّدٌ مِّنْ قَوَارِیْرَ قَالَتْ رَبِّ اِنِّیْ ظَلَمْتُ نَفْسِیْ وَاَسْلَمْتُ مَعَ سُلَیْمٰنَ لِلّٰهِ رَبِّ الْعٰلَمِیْنَ 

“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."”
