الكهف — Al-Kahf Ayat 98
قَالَ هٰذَا رَحْمَةٌ مِّنْ رَّبِّيْۚ فَاِذَا جَاۤءَ وَعْدُ رَبِّيْ جَعَلَهٗ دَكَّاۤءَۚ وَكَانَ وَعْدُ رَبِّيْ حَقًّا ۗ
Qāla hāżā raḥmatum mir rabbī, fa iżā jā'a wa‘du rabbī ja‘alahū dakkā'(a), wa kāna wa‘du rabbī ḥaqqā(n).
"[Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord true.""
