Aal-'Imran - 3:78

وَإِنَّ مِنْهُمْ لَفَرِيقًا يَلْوُونَ أَلْسِنَتَهُم بِالْكِتَابِ لِتَحْسَبُوهُ مِنَ الْكِتَابِ وَمَا هُوَ مِنَ الْكِتَابِ وَيَقُولُونَ هُوَ مِنْ عِندِ اللّهِ وَمَا هُوَ مِنْ عِندِ اللّهِ وَيَقُولُونَ عَلَى اللّهِ الْكَذِبَ وَهُمْ يَعْلَمُونَ
[3:78]
Most surely there is a party amongst those who distort the Book with their tongue that you may consider it to be (a part) of the Book, and they say, It is from Allah, while it is not from Allah, and they tell a lie against Allah whilst they know.
There is among them a section who distort the Book with their tongues: (As they read) you would think it is a part of the Book, but it is no part of the Book; and they say, "That is from Allah," but it is not from Allah: It is they who tell a lie against Allah, and (well) they know it!
And lo! there is a party of them who distort the Scripture with their tongues, that ye may think that what they say is from the Scripture, when it is not from the Scripture. And they say: It is from Allah, when it is not from Allah; and they speak a lie concerning Allah knowingly.
