Mankind was [of] one religion [before they divided into sects]; then God sent the prophets as bringers of good tidings and warners and sent down with them the Scripture in truth to judge between the people concerning that in which they differed. And none differed over the Scripture except those who were given it - after the clear proofs came to them - out of jealous animosity among themselves. And God guided those who believed to the truth concerning that over which they had differed, by His permission. And God guides whom He wills to a straight path.
40:53 - 44, Qur'an
And [so] We had certainly given Moses guidance, and We caused the Children of Israel to inherit the Scripture as guidance and a reminder for those of understanding.
6:84 - 87, Qur'an
And We gave to Abraham, Isaac and Jacob - all [of them] We guided. And Noah, We guided before; and among his descendants, and David and Solomon and Job and Joseph and Moses and Aaron. Thus do We reward the doers of good. And Zechariah and John and Jesus and Elijah - and all were of the righteous. And Ishmael and Elisha and Jonah and Lot - and all [of them] We preferred over the worlds. And [some] among their fathers and their descendants and their brothers - and We chose them and We guided them to a straight path.
And indeed, We sent down the Torah, in which was guidance and light. The prophets who submitted [to God] judged by it for the Jews, as did the rabbis and scholars by that with which they were entrusted of the Scripture of God, and they were witnesses thereto. So do not fear the people but fear Me, and do not exchange My verses for a small price. And whoever does not judge by what God has revealed - then it is those who are the disbelievers.
[For] indeed, We have revealed to you, as We revealed to Noah and the prophets after him. And We revealed to Abraham, Ishmael, Isaac, Jacob, the [twelve] tribes [of Israel], Jesus, Job, Jonah, Aaron, and Solomon, and to David We gave the Book [of Psalms].
[So] O you who have believed, believe in God and His messenger and the Book that He sent down upon His messenger and the Scripture which He sent down before. And whoever disbelieves in God, His Books, His messengers, His angels, and the Last Day has certainly gone far astray.
[So] say, "We have believed in God and in what was revealed to us and what was revealed to Abraham, Ishmael, Isaac, Jacob, and the [twelve] tribes [of Israel], and in what was given to Moses and Jesus and to the prophets from their Lord. We make no distinction between any of them, and we are submitting to Him."
God took a covenant from those who were given the Scripture, [saying], "You must make it clear to the people and not conceal it." But they threw it away behind their backs and exchanged it for a small price. And wretched is that which they purchased.
[2 Ezra 12:36 - 38], Torah
[For they said,] "You only have been meet to know this secret of the Highest. Therefore write all these things that you have seen in a book, and hide them; and teach them to the wise of the people, whose hearts you know may comprehend and keep these secrets."
[But] indeed, those who conceal what We sent down of clear proofs and guidance after We made it clear for the people in the Scripture - those are cursed by God and cursed by those who curse.
3:77 - 78, Qur'an
Indeed, those who exchange the covenant of God and their [own] oaths for a small price will have no share in the Hereafter, and God will not speak to them or look at them on the Day of Resurrection, nor will He purify them; and they will have a painful punishment. And indeed, there is among them a party who alter the Scripture with their tongues so you may think it is from the Scripture, but it is not from the Scripture. And they say, "This is from God," but it is not from God. And they speak untruth about God while they know.
Jeremiah 23:30 - 32, Torah
"Therefore, behold, I [am] against the prophets," the Lord says, "Who steal My words, everyone from his neighbor. Behold, I [am] against the prophets, who use their tongues and say, 'He says.' Behold, I [am] against those who prophesy false dreams, and tell them, and cause My people to err by their lies, and by their lightness; yet I did not send them, nor command them, therefore they will not profit this people at all."
Ezekiel 13:6 - 7, Torah
[For] they have seen vanity and lying divination, saying, "The Lord says," and the Lord has not sent them, and they have made [others] hope that they would confirm the word. Have you not seen a vain vision, and have you not spoken a lying divination, whereas you say, "The Lord says [it];" although I have not spoken?
22:52 - 54, Qur'an
[Thus] We did not send before you any messenger or prophet except that when he spoke [or recited], Satan threw into it [some misunderstanding]. But God abolishes that which Satan throws in; then God makes precise His verses. And God is Knowing and Wise. [That is] so He may make what Satan throws in a trial for those within whose hearts is disease and those hard of heart. And indeed, the wrongdoers are in extreme dissension. And so those who were given knowledge may know that it is the truth from your Lord and [therefore] believe in it, and their hearts humbly submit to it. And indeed is God the Guide of those who have believed to a straight path.
5:15 - 16, Qur'an
[So] O People of the Scripture, there has come to you Our messenger making clear to you much of what you used to conceal of the Scripture and overlooking much. There has come to you from God a light and a clear Book, by which God guides those who pursue His pleasure to the ways of peace and brings them out from darknesses into the light, by His permission, and guides them to a straight path.
And [so] We have revealed to you [O Muhammad], the Book in truth, confirming that which preceded it of the Scripture and as a criterion over it. So judge between them by what God has revealed and do not follow their inclinations away from what has come to you of the truth. To each of you We prescribed a law and a method. Had God willed, He would have made you one nation [united in religion], but [He intended] to test you in what He has given you; so race to [all that is] good. To God is your return all together, and He will [then] inform you concerning that over which you used to differ.
