The word(s) "losing" appears 3 time(s) in 3 verse(s) in Quran in Saheeh International translation.

(1) And they did not appraise Allah with true appraisal when they said, "Allah did not reveal to a human being anything." Say, "Who revealed the Scripture that Moses brought as light and guidance to the people? You [Jews] make it into pages, disclosing [some of] it and concealing much. And you were taught that which you knew not - neither you nor your fathers." Say, "Allah [revealed it]." Then leave them in their [empty] discourse, amusing themselves.

(2) Then did they feel secure from the plan of Allah? But no one feels secure from the plan of Allah except the losing people.

(3) They say, "That, then, would be a losing return."
