The word(s) "believer" appears 651 time(s) in 556 verse(s) in Quran in Mohsin Khan translation.

(181) Is it a wonder for mankind that We have sent Our Revelation to a man from among themselves (i.e. Prophet Muhammad صلى الله عليه وسلم) (saying): "Warn mankind (of the coming torment in Hell), and give good news to those who believe (in the Oneness of Allah and in His Prophet Muhammad صلى الله عليه وسلم) that they shall have with their Lord the rewards of their good deeds?" (But) the disbelievers say: "This is indeed an evident sorcerer (i.e. Prophet Muhammad صلى الله عليه وسلم and the Qur'an)!

(182) And indeed, We destroyed generations before you when they did wrong, while their Messengers came to them with clear proofs, but they were not such as to believe! Thus do We requite the people who are Mujrimun (disbelievers, polytheists, sinners, criminals).

(183) So who does more wrong than he who forges a lie against Allah or denies His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)? Surely, the Mujrimun (criminals, sinners, disbelievers and polytheists) will never be successful!

(184) Say: "Tell me, if His torment should come to you by night or by day, which portion thereof would the Mujrimun (disbelievers, polytheists, sinners, criminals) hasten on ?"

(185) O mankind! There has come to you a good advice from your Lord (i.e. the Qur'an, enjoining all that is good and forbidding all that is evil), and a healing for that (disease of ignorance, doubt, hypocrisy and differences) which is in your breasts, - a guidance and a mercy (explaining lawful and unlawful things) for the believers.

(186) Then after them We sent Musa (Moses) and Harun (Aaron) to Fir'aun (Pharaoh) and his chiefs with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). But they behaved arrogantly and were Mujrimun (disbelievers, sinners, polytheists, criminals) folk.

(187) "And Allah will establish and make apparent the truth by His Words, however much the Mujrimun (criminals, disbelievers, polytheists, sinners) may hate it."

(188) And We revealed to Musa (Moses) and his brother (saying): "Provide dwellings for your people in Egypt, and make your dwellings as places for your worship, and perform As-Salat (Iqamat-as-Salat ), and give glad tidings to the believers."

(189) And had your Lord willed, those on earth would have believed, all of them together. So, will you (O Muhammad صلى الله عليه وسلم) then compel mankind, until they become believers.

(190) Then (in the end) We save Our Messengers and those who believe! Thus it is incumbent upon Us to save the believers.
