Surah Al-Furqan, ayah 16

لَّهُمۡ فِيهَا مَا يَشَآءُونَ خَٰلِدِينَۚ كَانَ عَلَىٰ رَبِّكَ وَعۡدٗا مَّسۡـُٔولٗا ١٦

Llahum fīhā mā yashā'ūna khālidīna kāna 'alā rabbika wa'dam mas'ūlā

For them therein is whatever they wish, [while] abiding eternally. It is ever upon your Lord a promise [worthy to be] requested.¹⁰¹⁰
