The word(s) "lose" appears 65 time(s) in 62 verse(s) in Quran in Muhammad Pickthal translation.

(41) Say: It may be that a part of that which ye would hasten on is close behind you.

(42) Say (unto them, O Muhammad): Allah sufficeth for witness between me and you. He knoweth whatsoever is in the heavens and the earth. And those who believe in vanity and disbelieve in Allah, they it is who are the losers.

(43) The Prophet is closer to the believers than their selves, and his wives are (as) their mothers. And the owners of kinship are closer one to another in the ordinance of Allah than (other) believers and the fugitives (who fled from Mecca), except that ye should do kindness to your friends. This is written in the Book (of nature).

(44) O Prophet! Tell thy wives and thy daughters and the women of the believers to draw their cloaks close round them (when they go abroad). That will be better, so that they may be recognised and not annoyed. Allah is ever Forgiving, Merciful.

(45) (Shown in their) behaving arrogantly in the land and plotting evil; and the evil plot encloseth but the men who make it. Then, can they expect aught save the treatment of the folk of old? Thou wilt not find for Allah's way of treatment any substitute, nor wilt thou find for Allah's way of treatment aught of power to change.

(46) Then worship what ye will beside Him. Say: The losers will be those who lose themselves and their housefolk on the Day of Resurrection. Ah, that will be the manifest loss!

(47) His are the keys of the heavens and the earth, and they who disbelieve the revelations of Allah - such are they who are the losers.

(48) And verily it hath been revealed unto thee as unto those before thee (saying): If thou ascribe a partner to Allah thy work will fail and thou indeed wilt be among the losers.

(49) And We assigned them comrades (in the world), who made their present and their past fairseeming unto them. And the Word concerning nations of the jinn and humankind who passed away before them hath effect for them. Lo! they were ever losers.

(50) And thou wilt see them exposed to (the Fire), made humble by disgrace, and looking with veiled eyes. And those who believe will say: Lo! the (eternal) losers are they who lose themselves and their housefolk on the Day of Resurrection. Lo! are not the wrong-doers in perpetual torment?
