Surah An-Naml, verse 44

قِيلَ لَهَا ٱدْخُلِى ٱلصَّرْحَ ۖ فَلَمَّا رَأَتْهُ حَسِبَتْهُ لُجَّةً وَكَشَفَتْ عَن سَاقَيْهَا ۚ قَالَ إِنَّهُۥ صَرْحٌ مُّمَرَّدٌ مِّن قَوَارِيرَ ۗ قَالَتْ رَبِّ إِنِّى ظَلَمْتُ نَفْسِى وَأَسْلَمْتُ مَعَ سُلَيْمَـٰنَ لِلَّهِ رَبِّ ٱلْعَـٰلَمِينَ ﴿٤٤﴾

27:44 It was said to her, “Enter the palace.” But when she saw it, she thought it was a body of water, 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.”
