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

(31) Evil is the parable of the people who rejected Our Ayat (proofs, evidence, verses and signs, etc.), and used to wrong their ownselves.

(32) Those who reject Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), We shall gradually seize them with punishment in ways they perceive not.

(33) (And remember) when you (the Muslim army) were on the near side of the valley, and they on the farther side, and the caravan on the ground lower than you. Even if you had made a mutual appointment to meet, you would certainly have failed in the appointment, but (you met) that Allah might accomplish a matter already ordained (in His Knowledge), so that those who were to be destroyed (for their rejecting the Faith) might be destroyed after a clear evidence, and those who were to live (i.e. believers) might live after a clear evidence. And surely, Allah is All-Hearer, All-Knower.

(34) Similar to the behaviour of the people of Fir'aun (Pharaoh), and of those before them - they rejected the Ayat (proofs, verses, etc.) of Allah, so Allah punished them for their sins. Verily, Allah is All-Strong, Severe in punishment.

(35) Then after him We sent Messengers to their people. They brought them clear proofs, but they would not believe what they had already rejected beforehand. Thus We seal the hearts of the transgressors (those who disbelieve in the Oneness of Allah and disobey Him).

(36) Can they (Muslims) who rely on a clear proof (the Qur'an) from their Lord, and whom a witness [Jibril (Gabriel عليه السلام)] from Him recites (follows) it (can they be equal with the disbelievers); and before it, came the Book of Musa (Moses), a guidance and a mercy, they believe therein, but those of the sects (Jews, Christians and all the other non-Muslim nations) that reject it (the Qur'an), the Fire will be their promised meeting-place. So be not in doubt about it (i.e. those who denied Prophet Muhammad صلى الله عليه و سلم and also denied all that which he brought from Allah. Surely, they will enter Hell). Verily, it is the truth from your Lord, but most of the mankind believe not.

(37) Such were 'Ad (people). They rejected the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord and disobeyed His Messengers, and followed the command of every proud obstinate (oppressor of the truth, from their leaders).

(38) Those to whom We have given the Book (such as 'Abdullah bin Salam and other Jews who embraced Islam), rejoice at what has been revealed unto you (i.e. the Qur'an), but there are among the Confederates (from the Jews and pagans) those who reject a part thereof. Say (O Muhammad صلى الله عليه و سلم): "I am commanded only to worship Allah (Alone) and not to join partners with Him. To Him (Alone) I call and to Him is my return."

(39) Whoever desires the quick-passing (transitory enjoyment of this world), We readily grant him what We will for whom We like. Then, afterwards, We have appointed for him Hell; he will burn therein disgraced and rejected (- far away from Allah's Mercy).

(40) This is (part) of Al-Hikmah (wisdom, good manners and high character) which your Lord has revealed to you (O Muhammad صلى الله عليه و سلم). And set not up with Allah any other ilah (god) lest you should be thrown into Hell, blameworthy and rejected, (from Allah's Mercy).
