The word(s) "lost" appears 16 time(s) in 16 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) And certainly We sent apostles before you: there are some of them that We have mentioned to you and there are others whom We have not mentioned to you, and it was not meet for an apostle that he should bring a sign except with Allah's permission, but when the command of Allah came, judgment was given with truth, and those who treated (it) as a lie were lost.

(12) But their belief was not going to profit them when they had seen Our punishment; (this is) Allah's law, which has indeed obtained in the matter of His servants, and there the unbelievers are lost.

(13) And that was your (evil) thought which you entertained about your Lord that has tumbled you down into perdition, so are you become of the lost ones.

(14) And you shall see them brought before it humbling themselves because of the abasements, looking with a faint glance. And those who believe shall say: Surely the losers are they who have lost themselves and their followers on the resurrection day. Now surely the iniquitous shall remain in lasting chastisement.

(15) Why did not then those help them whom they took for gods besides Allah to draw (them) nigh (to Him)? Nay! they were lost to them; and this was their lie and what they forged.

(16) And find you lost (that is, unrecognized by men) and guide (them to you)?
