The word(s) "faction" appears 25 time(s) in 21 verse(s) in Quran in Saheeh International translation.

(1) A faction of the people of the Scripture wish they could mislead you. But they do not mislead except themselves, and they perceive [it] not.

(2) And a faction of the People of the Scripture say [to each other], "Believe in that which was revealed to the believers at the beginning of the day and reject it at its end that perhaps they will abandon their religion,

(3) Then after distress, He sent down upon you security [in the form of] drowsiness, overcoming a faction of you, while another faction worried about themselves, thinking of Allah other than the truth - the thought of ignorance, saying, "Is there anything for us [to have done] in this matter?" Say, "Indeed, the matter belongs completely to Allah." They conceal within themselves what they will not reveal to you. They say, "If there was anything we could have done in the matter, some of us would not have been killed right here." Say, "Even if you had been inside your houses, those decreed to be killed would have come out to their death beds." [It was] so that Allah might test what is in your breasts and purify what is in your hearts. And Allah is Knowing of that within the breasts.

(4) And give the women [upon marriage] their [bridal] gifts graciously. But if they give up willingly to you anything of it, then take it in satisfaction and ease.

(7) So is one who [stands] upon a clear evidence from his Lord [like the aforementioned]? And a witness from Him follows it, and before it was the Scripture of Moses to lead and as mercy. Those [believers in the former revelations] believe in the Qur'an. But whoever disbelieves in it from the [various] factions - the Fire is his promised destination. So be not in doubt about it. Indeed, it is the truth from your Lord, but most of the people do not believe.

(8) And [the believers among] those to whom We have given the [previous] Scripture rejoice at what has been revealed to you, [O Muhammad], but among the [opposing] factions are those who deny part of it. Say, "I have only been commanded to worship Allah and not associate [anything] with Him. To Him I invite, and to Him is my return."

(9) Then We awakened them that We might show which of the two factions was most precise in calculating what [extent] they had remained in time.

(10) Then the factions differed [concerning Jesus] from among them, so woe to those who disbelieved - from the scene of a tremendous Day.
