18:54We have elaborated in this Quran for the people every kind of example, but the human being is a most argumentative being.

18:84We established him on earth, and gave him all kinds of means.

18:86Until, when he reached the setting of the sun, he found it setting in a murky spring, and found a people in its vicinity. We said, “O Zul-Qarnain, you may either inflict a penalty, or else treat them kindly.”
