The word(s) "bought" appears 4 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) Those are they who have bought the life of this world at the price of the Hereafter. Their torment shall not be lightened nor shall they be helped.

(2) (And remember) when Allah took a covenant from those who were given the Scripture (Jews and Christians) to make it (the news of the coming of Prophet Muhammad صلى الله عليه وسلم and the religious knowledge) known and clear to mankind, and not to hide it, but they threw it away behind their backs, and purchased with it some miserable gain! And indeed worst is that which they bought.

(3) And he (the man) from Egypt who bought him, said to his wife: "Make his stay comfortable, may be he will profit us or we shall adopt him as a son." Thus did We establish Yusuf (Joseph) in the land, that We might teach him the interpretation of events. And Allah has full power and control over His Affairs, but most of men know not.

(4) And [Yusuf (Joseph)] told his servants to put their money (with which they had bought the corn) into their bags, so that they might know it when they go back to their people; in order they might come again.
