Qur'an 3:78

وَإِنَّ مِنْهُمْ لَفَرِيقًا يَلْوُۥنَ أَلْسِنَتَهُم بِٱلْكِتَـٰبِ لِتَحْسَبُوهُ مِنَ ٱلْكِتَـٰبِ وَمَا هُوَ مِنَ ٱلْكِتَـٰبِ وَيَقُولُونَ هُوَ مِنْ عِندِ ٱللَّهِ وَمَا هُوَ مِنْ عِندِ ٱللَّهِ وَيَقُولُونَ عَلَى ٱللَّهِ ٱلْكَذِبَ وَهُمْ يَعْلَمُونَ

“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 Allāh," but it is not from Allāh. And they speak untruth about Allāh while they know.”
