The word(s) "bought" appears 2 time(s) in 2 verse(s) in Quran in Saheeh International translation.

(1) Those are the ones who have bought the life of this world [in exchange] for the Hereafter, so the punishment will not be lightened for them, nor will they be aided.

(2) And the one from Egypt who bought him said to his wife, "Make his residence comfortable. Perhaps he will benefit us, or we will adopt him as a son." And thus, We established Joseph in the land that We might teach him the interpretation of events. And Allah is predominant over His affair, but most of the people do not know.
