الكهف
86 / 110
حَتَّىٰٓ إِذَا بَلَغَ مَغْرِبَ ٱلشَّمْسِ وَجَدَهَا تَغْرُبُ فِى عَيْنٍ حَمِئَةٍ وَوَجَدَ عِندَهَا قَوْمًا ۗ قُلْنَا يَـٰذَا ٱلْقَرْنَيْنِ إِمَّآ أَن تُعَذِّبَ وَإِمَّآ أَن تَتَّخِذَ فِيهِمْ حُسْنًا
then, when he came to the setting of the sun, he found it [seemed to be] setting into a muddy spring. Nearby he found some people and We said, ‘Dhu ’l-Qarnayn, you may choose [which of them] to punish or show kindness to.’
