(18:81) So we intended that their Lord should substitute for them one better than him in purity and nearer to mercy. (18:82) And as for the wall, it belonged to two orphan boys in the city, and there was beneath it a treasure for them, and their father had been righteous. So your Lord intended that they reach maturity and extract their treasure, as a mercy from your Lord. And I did it not of my own accord. That is the interpretation of that about which you could not have patience." (18:83) And they ask you, [O Muhammad], about Dhul-Qarnayn. Say, "I will recite to you about him a report." (18:84) Indeed We established him upon the earth, and We gave him to everything a way. (18:85) So he followed a way (18:86) Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people. Allah said, "O Dhul-Qarnayn, either you punish [them] or else adopt among them [a way of] goodness." (18:87) He said, "As for one who wrongs, we will punish him. Then he will be returned to his Lord, and He will punish him with a terrible punishment.
