The word(s) "reject" appears 60 time(s) in 56 verse(s) in Quran in Mohsin Khan translation.

(11) Verily, those who disbelieve in Allah and His Messengers and wish to make distinction between Allah and His Messengers (by believing in Allah and disbelieving in His Messengers) saying, "We believe in some but reject others," and wish to adopt a way in between.

(12) Because of their breaking the covenant, and of their rejecting the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, and of their killing the Prophets unjustly, and of their saying: "Our hearts are wrapped (with coverings, i.e. we do not understand what the Messengers say)" - nay, Allah has set a seal upon their hearts because of their disbelief, so they believe not but a little.

(13) The Messiah will never be proud to reject to be a slave to Allah, nor the angels who are the near (to Allah). And whosoever rejects His worship and is proud, then He will gather them all together unto Himself.

(14) O Messenger (Muhammad صلى الله عليه وسلم)! Let not those who hurry to fall into disbelief grieve you, of such who say: "We believe" with their mouths but their hearts have no faith. And of the Jews are men who listen much and eagerly to lies - listen to others who have not come to you. They change the words from their places; they say, "If you are given this, take it, but if you are not given this, then beware!" And whomsoever Allah wants to put in Al-Fitnah [error, because of his rejecting of Faith], you can do nothing for him against Allah. Those are the ones whose hearts Allah does not want to purify (from disbelief and hypocrisy); for them there is a disgrace in this world, and in the Hereafter a great torment.

(15) Indeed, they rejected the truth (the Qur'an and Muhammad صلى الله عليه وسلم) when it came to them, but there will come to them the news of that (the torment) which they used to mock at.

(16) Say (O Muhammad صلى الله عليه وسلم): "Travel in the land and see what was the end of those who rejected truth."

(17) And who does more aggression and wrong than he who invents a lie against Allah or rejects His Ayat (proofs, evidence, verses, lessons or revelations)? Verily, the Zalimun (polytheists and wrong-doers) shall never be successful.

(18) Those who reject Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) are deaf and dumb in the darkness. Allah sends astray whom He wills and He guides on the Straight Path whom He wills.

(19) But those who reject Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), the torment will touch them for their disbelief (and for their belying the Message of Muhammad صلى الله عليه وسلم). [Tafsir Al-Qurtubi].

(20) And who can be more unjust than he who invents a lie against Allah, or says: "A revelation has come to me" whereas no revelation has come to him in anything ; and who says, "I will reveal the like of what Allah has revealed." And if you could but see when the Zalimun (polytheists and wrong-doers) are in the agonies of death, while the angels are stretching forth their hands (saying): "Deliver your souls! This day you shall be recompensed with the torment of degradation because of what you used to utter against Allah other than the truth. And you used to reject His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) with disrespect! "
