18:86
حَتَّىٰۤ إِذَا بَلَغَ مَغۡرِبَ ٱلشَّمۡسِ وَجَدَهَا تَغۡرُبُ فِی عَیۡنٍ حَمِئَةࣲ وَوَجَدَ عِندَهَا قَوۡمࣰاۖ قُلۡنَا یَـٰذَا ٱلۡقَرۡنَیۡنِ إِمَّاۤ أَن تُعَذِّبَ وَإِمَّاۤ أَن تَتَّخِذَ فِیهِمۡ حُسۡنࣰا
Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout. We said: O Dhu'l-Qarneyn! Either punish or show them kindness.
