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

(61) Have you not seen those who were given a portion of the Scripture? They believe in Jibt and Taghut and say to the disbelievers that they are better guided as regards the way than the believers (Muslims).

(62) Let those (believers) who sell the life of this world for the Hereafter fight in the Cause of Allah, and whoso fights in the Cause of Allah, and is killed or gets victory, We shall bestow on him a great reward.

(63) Then fight (O Muhammad صلى الله عليه وسلم) in the Cause of Allah, you are not tasked (held responsible) except for yourself, and incite the believers (to fight along with you), it may be that Allah will restrain the evil might of the disbelievers. And Allah is Stronger in Might and Stronger in punishing.

(64) It is not for a believer to kill a believer except (that it be) by mistake; and whosoever kills a believer by mistake, (it is ordained that) he must set free a believing slave and a compensation (blood-money, i.e. Diya) be given to the deceased's family unless they remit it. If the deceased belonged to a people at war with you and he was a believer, the freeing of a believing slave (is prescribed); and if he belonged to a people with whom you have a treaty of mutual alliance, compensation (blood-money - Diya) must be paid to his family, and a believing slave must be freed. And whoso finds this (the penance of freeing a slave) beyond his means, he must fast for two consecutive months in order to seek repentance from Allah. And Allah is Ever All-Knowing, All-Wise.

(65) And whoever kills a believer intentionally, his recompense is Hell to abide therein; and the Wrath and the Curse of Allah are upon him, and a great punishment is prepared for him.

(66) O you who believe! When you go (to fight) in the Cause of Allah, verify (the truth), and say not to anyone who greets you (by embracing Islam): "You are not a believer"; seeking the perishable goods of the worldly life. There are much more profits and booties with Allah. Even as he is now, so were you yourselves before till Allah conferred on you His Favours (i.e. guided you to Islam), therefore, be cautious in discrimination. Allah is Ever Well-Aware of what you do.

(67) Not equal are those of the believers who sit (at home), except those who are disabled (by injury or are blind or lame), and those who strive hard and fight in the Cause of Allah with their wealth and their lives. Allah has preferred in grades those who strive hard and fight with their wealth and their lives above those who sit (at home). Unto each, Allah has promised good (Paradise), but Allah has preferred those who strive hard and fight, above those who sit (at home) by a huge reward.

(68) Verily! As for those whom the angels take (in death) while they are wronging themselves (as they stayed among the disbelievers even though emigration was obligatory for them), they (angels) say (to them): "In what (condition) were you?" They reply: "We were weak and oppressed on the earth." They (angels) say: "Was not the earth of Allah spacious enough for you to emigrate therein?" Such men will find their abode in Hell - What an evil destination!

(69) And when you (Muslims) travel in the land, there is no sin on you if you shorten As-Salat (the prayer) if you fear that the disbelievers may put you in trial (attack you etc.), verily, the disbelievers are ever unto you open enemies.

(70) When you (O Messenger Muhammad صلى الله عليه وسلم) are among them, and lead them in As-Salat (the prayer), let one party of them stand up [in Salat (prayer)] with you taking their arms with them; when they finish their prostrations, let them take their positions in the rear and let the other party come up which have not yet prayed, and let them pray with you taking all the precautions and bearing arms. Those who disbelieve wish, if you were negligent of your arms and your baggage, to attack you in a single rush, but there is no sin on you if you put away your arms because of the inconvenience of rain or because you are ill, but take every precaution for yourselves. Verily, Allah has prepared a humiliating torment for the disbelievers.
