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

(151) And We send not the Messengers except as givers of glad tidings and warners. But those who disbelieve, dispute with false argument, in order to refute the truth thereby. And they treat My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and that with which they are warned, as a jest and mockery!

(152) And who does more wrong than he who is reminded of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord, but turns away from them, forgetting what (deeds) his hands have sent forth. Truly, We have set veils over their hearts lest they should understand this (the Qur'an), and in their ears, deafness. And if you (O Muhammad صلى الله عليه وسلم) call them to guidance, even then they will never be guided.

(153) "They are those who deny the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord and the Meeting with Him (in the Hereafter). So their works are in vain, and on the Day of Resurrection, We shall assign no weight for them.

(154) "That shall be their recompense, Hell; because they disbelieved and took My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and My Messengers by way of jest and mockery.

(155) "And He has made me blessed wheresoever I be, and has enjoined on me Salat (prayer), and Zakat, as long as I live."

(156) And warn them (O Muhammad صلى الله عليه وسلم) of the Day of grief and regrets, when the case has been decided, while (now) they are in a state of carelessness, and they believe not .

(157) "Go you and your brother with My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and do not, you both, slacken and become weak in My Remembrance.

(158) And thus We have sent it down as a Qur'an in Arabic, and have explained therein in detail the warnings, in order that they may fear Allah, or that it may cause them to have a lesson from it (or to have the honour for believing and acting on its teachings).

(159) (Allah) will say: "Like this: Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) came unto you, but you disregarded them (i.e. you left them, did not think deeply in them, and you turned away from them), and so this Day, you will be neglected (in the Hell-fire, away from Allah's Mercy)."

(160) And thus do We requite him who transgresses beyond bounds [i.e. commits the great sins and disobeys his Lord (Allah) and believes not in His Messengers, and His revealed Books, like this Qur'an], and believes not in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord; and the torment of the Hereafter is far more severe and more lasting.
