Surah Al-Kahf Ayahs #91 Translated in English

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 [i.e., Hellfire].

But as for one who believes and does righteousness, he will have a reward of the best [i.e., Paradise], and we [i.e., Dhul-Qarnayn] will speak to him from our command with ease."

Then he followed a way

Until, when he came to the rising of the sun [i.e., the east], he found it rising on a people for whom We had not made against it any shield.

Thus. And We had encompassed [all] that he had in knowledge.
