18:98
قَالَ هَـٰذَا رَحْمَةٌ مِّن رَّبِّى ۖ فَإِذَا جَآءَ وَعْدُ رَبِّى جَعَلَهُۥ دَكَّآءَ ۖ وَكَانَ وَعْدُ رَبِّى حَقًّا٩٨
[Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord1 comes [i.e., approaches], He will make it level, and ever is the promise of my Lord true."
