The word(s) "lose" appears 75 time(s) in 72 verse(s) in Quran in Mohsin Khan translation.

(61) It is Allah Who has sent down the Book (the Qur'an) in truth, and the Balance (i.e. to act justly). And what can make you know that perhaps the Hour is close at hand?

(62) And you will see them brought forward to it (Hell) made humble by disgrace, (and) looking with stealthy glance. And those who believe will say: "Verily, the losers are they who lose themselves and their families on the Day of Resurrection. Verily, the Zalimun [i.e. Al-Kafirun (disbelievers in Allah, in His Oneness and in His Messenger صلى الله عليه و سلم, polytheists, wrong-doers)] will be in a lasting torment. (Tafsir At-Tabari).

(63) And to Allah belongs the kingdom of the heavens and the earth. And on the Day that the Hour will be established - on that Day the followers of falsehood (polytheists, disbelievers, worshippers of false deities) shall lose (everything).

(64) They are those against whom the Word (of torment) is justified among the previous generations of jinn and mankind that have passed away. Verily, they are ever the losers.

(65) Then he [Jibril (Gabriel)] approached and came closer,

(66) Shaitan (Satan) has overpowered them. So he has made them forget the remembrance of Allah. They are the party of Shaitan (Satan). Verily, it is the party of Shaitan (Satan) that will be the losers!

(67) O you who believe! Let not your properties or your children divert you from the remembrance of Allah. And whosoever does that, then they are the losers.

(68) And (remember) when the Prophet (صلى الله عليه وسلم) disclosed a matter in confidence to one of his wives (Hafsah), then she told it (to another i.e. 'Aishah). And Allah made it known to him; he informed part thereof and left a part. Then when he told her (Hafsah) thereof, she said: "Who told you this?" He said: "The All-Knower, the All-Aware (Allah) has told me."

(69) And whether you keep your talk secret or disclose it, Verily, He is the All-Knower of what is in the breasts (of men).

(70) And the shade thereof is close upon them, and the bunches of fruit thereof will hang low within their reach.
