The word(s) "religion" appears 87 time(s) in 76 verse(s) in Quran in Muhammad Pickthal translation.

(31) But if they repent and establish worship and pay the poor-due, then are they your brethren in religion. We detail Our revelations for a people who have knowledge.

(32) And if they break their pledges after their treaty (hath been made with you) and assail your religion, then fight the heads of disbelief - Lo! they have no binding oaths - in order that they may desist.

(33) Fight against such of those who have been given the Scripture as believe not in Allah nor the Last Day, and forbid not that which Allah hath forbidden by His messenger, and follow not the religion of Truth, until they pay the tribute readily, being brought low.

(34) He it is Who hath sent His messenger with the guidance and the religion of Truth, that He may cause it to prevail over all religion, however much the idolaters may be averse.

(35) Lo! the number of the months with Allah is twelve months by Allah's ordinance in the day that He created the heavens and the earth. Four of them are sacred: that is the right religion. So wrong not yourselves in them. And wage war on all of the idolaters as they are waging war on all of you. And know that Allah is with those who keep their duty (unto Him).

(36) And the believers should not all go out to fight. Of every troop of them, a party only should go forth, that they (who are left behind) may gain sound knowledge in religion, and that they may warn their folk when they return to them, so that they may beware.

(37) Say (O Muhammad): O mankind! If ye are in doubt of my religion, then (know that) I worship not those whom ye worship instead of Allah, but I worship Allah Who causeth you to die, and I have been commanded to be of the believers.

(38) And, (O Muhammad) set thy purpose resolutely for religion, as a man by nature upright, and be not of those who ascribe partners (to Allah).

(39) He said: The food which ye are given (daily) shall not come unto you but I shall tell you the interpretation ere it cometh unto you. This is of that which my Lord hath taught me. Lo! I have forsaken the religion of folk who believe not in Allah and are disbelievers in the Hereafter.

(40) And I have followed the religion of my fathers, Abraham and Isaac and Jacob. It never was for us to attribute aught as partner to Allah. This is of the bounty of Allah unto us (the seed of Abraham) and unto mankind; but most men give not thanks.
