The Cow - 2:217
"They ask you about fighting in the Holy Month. Say: "Fighting on it is a great sin. But to turn away from the way of Allah and to be ungrateful to Him and to the Holy Mosque and to drive out its people from it is a greater sin with Allah. For oppression and cruelty is a greater crime than killing."If they could, they would fight you until they turn you back from your religion. Whoever of you turns away from his religion and dies as an unbeliever, all that he did will be in vain in this world and in the Hereafter. They are the people of the Fire and will abide therein forever."
A reference to the hypocrites of the people of the Book who mislead the believers by attempting to change the way of Allah:
The Women/4:44
Do you not see that those who have been given a share of the Book have bought error and wish that you should go astray?
The Family Of Imran/3:69
A group of the people of the Book want to lead you astray. They only mislead themselves. They do not even realize it.
The Family Of Imran/3:70
People of the Book! Why do you deny the Verses of Allah while you are witnesses?
The Family Of Imran/3:71
People of the Book! Why do you confuse right and wrong and knowingly conceal the truth?
The Family Of Imran/3:72
"A group of the people of the Book said: "Believe in what has been sent down to the believers at the beginning of the day and disbelieve at the end. So that perhaps they may turn away from their religion."
The Cow/2:120
"Neither the Jews nor the Christians will be pleased with you unless you enter into their religion. Say: "The right way is the way of Allah."If you follow their desires after the knowledge that has come to you, you will find neither a friend nor a supporter to defend you against Allah."
The Repentance/9:31
They took the scribes and the religious leaders and the Messiah, the son of Mary, as gods apart from God. But they were commanded to serve only one God. There is no god but Him. And He is Most High from those whom they associate as partners.
The Ornaments of Gold/43:57
When the son of Mary was shown as an example, your people immediately rejected.
The Ornaments of Gold/43:58
"They said: "Are our gods better or is he?"They said this only to argue with you. They are indeed a quarrelsome people."
The Hypocrites/63:1
"When the hypocrites come to you, they say, "We bear witness that you are the messenger of Allah. Allah knows that you are His messenger, and Allah testifies that the hypocrites lie."
The Hypocrites/63:2
They take their oaths as a shield and lead astray from the way of Allah. How evil is what they do.
The Hypocrites/63:3
Because they disbelieved after they believed, so their hearts were sealed; they do not understand.
The Women/4:51
"Do you not see those who have been given a share of the Book? They believe in idolatry and false doctrines, and say of those who disbelieve, "These are more rightly guided than those who believe"."
The Women/4:60
Do you not see those who claim to believe in you and in what has been sent down to you and in what has been sent down before you, but they want to follow the laws of the unjust and despotic, while they were commanded to disbelieve in it, but Satan wants to lead them astray.
The Women/4:88
Why do you divide yourselves into two groups about the hypocrites? Allah has turned them upside down because of what they used to do. Do you want to guide those whom Allah has led astray? You will find no way for him whom Allah has led astray.
The Women/4:89
They wanted you to disbelieve as they disbelieved so that you might become one with them. Do not take any of them as friends until they take action in the way of Allah. If they turn against you, seize them and kill them wherever you find them. Take them neither as friends nor as helpers;
The Cow/2:135
"They said: "Become Jews or Christians so that you may be guided". Say: "No, we follow the monotheistic religion of Abraham. He was not of those who associate partners."
The Cow/2:140
"Do you claim that Abraham, Ishmael, Isaac, Jacob and their descendants were Jews or Christians? Say: "Do you know better or Allah? Who is more unjust than he who conceals what Allah has revealed? Allah is not heedless of what you do."
The Family Of Imran/3:65
O people of the Book, why do you dispute about Abraham, when the Injeel and the Torah were sent down after him? Do you not use your intellect?
The Family Of Imran/3:66
You argue about matters about which you have knowledge! But how can you argue about something about which you have no knowledge? You may not know, but Allah knows.
The Family Of Imran/3:67
Abraham was neither a Jew nor a Christian; he was a monotheistic Muslim. He was never of those who associate partners.
The Family Of Imran/3:68
The closest of mankind to Abraham are those who follow him, this prophet and those who believe. Allah is the sovereign and the friend of the believers.
The Family Of Imran/3:78
"Some of them try to make what is not in the Book resemble the Book by twisting their tongues so that you may think that what is not in the Book is in the Book, and they say, "This is from Allah"when it is not from Allah. They knowingly lie in the name of Allah."
The Family Of Imran/3:100
Believers! If you follow some of the people of the Book, they will turn you back to disbelief after you have believed.
The Family Of Imran/3:101
How can you disbelieve when the verses of Allah are recited to you and His messenger is among you? Whoever clings to Allah is guided to the straight path.
