The word(s) "half" appears 15 time(s) in 15 verse(s) in Quran in Muhammad Pickthal translation.

(11) And when the awe departed from Abraham, and the glad news reached him, he pleaded with Us on behalf of the folk of Lot.

(12) Then We inspired in him, saying: Make the ship under Our eyes and Our inspiration. Then, when Our command cometh and the oven gusheth water, introduce therein of every (kind) two spouses, and thy household save him thereof against whom the Word hath already gone forth. And plead not with Me on behalf of those who have done wrong. Lo! they will be drowned.

(13) They it is who say: Spend not on behalf of those (who dwell) with Allah's messenger that they may disperse (and go away from you); when Allah's are the treasures of the heavens and the earth; but the hypocrites comprehend not.

(14) A half thereof, or abate a little thereof

(15) Lo! thy Lord knoweth how thou keepest vigil sometimes nearly two-thirds of the night, or (sometimes) half or a third thereof, as do a party of those with thee. Allah measureth the night and the day. He knoweth that ye count it not, and turneth unto you in mercy. Recite, then, of the Qur'an that which is easy for you. He knoweth that there are sick folk among you, while others travel in the land in search of Allah's bounty, and others (still) are fighting for the cause of Allah. So recite of it that which is easy (for you), and establish worship and pay the poor-due, and (so) lend unto Allah a goodly loan. Whatsoever good ye send before you for your souls, ye will find it with Allah, better and greater in the recompense. And seek forgiveness of Allah. Lo! Allah is Forgiving, Merciful.
