The word(s) "less" appears 345 time(s) in 333 verse(s) in Quran in Mohsin Khan translation.

(311) And those who believe in (the Oneness of) Allah and His Messengers - they are the Siddiqun (i.e. those followers of the Prophets who were first and foremost to believe in them), and the martyrs with their Lord, they shall have their reward and their light. But those who disbelieve (in the Oneness of Allah - Islamic Monotheism) and deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) - they shall be the dwellers of the blazing Fire.

(312) Verily, those who oppose Allah and His Messenger (Muhammad صلى الله عليه وسلم) will be disgraced, as those before them (among the past nation) were disgraced. And We have sent down clear Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). And for the disbelievers is a disgracing torment.

(313) Have you not seen that Allah knows whatsoever is in the heavens and whatsoever is on the earth? There is no Najwa (secret counsel) of three but He is their fourth (with His Knowledge, while He Himself is over the Throne, over the seventh heaven), nor of five but He is their sixth (with His Knowledge), nor of less than that or more but He is with them (with His Knowledge) wheresoever they may be. And afterwards on the Day of Resurrection He will inform them of what they did. Verily, Allah is the All-Knower of everything.

(314) And also (He will give you) another (blessing) which you love, - help from Allah (against your enemies) and a near victory. And give glad tidings (O Muhammad صلى الله عليه وسلم) to the believers.

(315) But those who disbelieved (in the Oneness of Allah - Islamic Monotheism) and denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they will be the dwellers of the Fire, to dwell therein forever. And worst indeed is that destination .

(316) Blessed be He in Whose Hand is the dominion; and He is Able to do all things.

(317) And Verily, for you (O Muhammad صلى الله عليه وسلم) will be an endless reward.

(318) And (O Muhammad صلى الله عليه وسلم) obey you not everyone Hallaf Mahin (the one who swears much and is a liar or is worthless). [Tafsir At-Tabari]

(319) Till, when they see that which they are promised, then they will know who it is that is weaker concerning helpers and less important concerning numbers.

(320) Half of it or a little less than that,
