The word(s) "disbelievers" appears 347 time(s) in 327 verse(s) in Quran in Mohsin Khan translation.

(241) Verily, those who turn away from Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc. by attacking, distorting and denying them) are not hidden from Us. Is he who is cast into the Fire better or he who comes secure on the Day of Resurrection? Do what you will. Verily He is All-Seer of what you do (this is a severe threat to the disbelievers ).

(242) And truly, if We give him a taste of mercy from Us, after some adversity (severe poverty or disease, etc.) has touched him, he is sure to say: "This is due to my (merit); I think not that the Hour will be established. But if I am brought back to my Lord, surely, there will be for me the best (wealth) with Him. Then, We verily, will show to the disbelievers what they have done, and We shall make them taste a severe torment.

(243) And He answers (the invocation of) those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, and gives them increase of His Bounty. And as for the disbelievers, theirs will be a severe torment.

(244) And you will see them brought forward to it (Hell) made humble by disgrace, (and) looking with stealthy glance. And those who believe will say: "Verily, the losers are they who lose themselves and their families on the Day of Resurrection. Verily, the Zalimun [i.e. Al-Kafirun (disbelievers in Allah, in His Oneness and in His Messenger صلى الله عليه و سلم, polytheists, wrong-doers)] will be in a lasting torment. (Tafsir At-Tabari).

(245) And when the truth (this Qur'an) came to them, they (the disbelievers in this Qur'an) said: "This is magic, and we disbelieve therein."

(246) And were it not that mankind would have become of one community (all disbelievers, desiring worldly life only), We would have provided for those who disbelieve in the Most Gracious (Allah), silver roofs for their houses, and elevators whereby they ascend,

(247) Verily, the Mujrimun (criminals, sinners, disbelievers) will be in the torment of Hell to abide therein forever.

(248) (But they were aggressive), so he [Musa (Moses)] called upon his Lord (saying): "These are indeed the people who are Mujrimun (disbelievers, polytheists, sinners, criminals)."

(249) Are they better or the people of Tubba' and those before them? We destroyed them because they were indeed Mujrimun (disbelievers, polytheists, sinners, criminals).

(250) Say (O Muhammad صلى الله عليه و سلم) to the believers to forgive those who (harm them and) hope not for the Days of Allah (i.e. His Recompense), that He may recompense people, according to what they have earned (i.e. to punish these disbelievers who harm the believers).
