Surah An-Naml, Verse 44
قِيلَ لَهَا ٱدْخُلِى ٱلصَّرْحَ ۖ فَلَمَّا رَأَتْهُ حَسِبَتْهُ لُجَّةًۭ وَكَشَفَتْ عَن سَاقَيْهَا ۚ قَالَ إِنَّهُۥ صَرْحٌۭ مُّمَرَّدٌۭ مِّن قَوَارِيرَ ۗ قَالَتْ رَبِّ إِنِّى ظَلَمْتُ نَفْسِى وَأَسْلَمْتُ مَعَ سُلَيْمَٰنَ لِلَّهِ رَبِّ ٱلْعَٰلَمِينَ
Translation — Sahih International
She was told, "Enter the palace." But when she saw it, she thought it was a body of water 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 Allah, Lord of the worlds."
