Quran 3:78 from Surah Aal-i-Imraan on Divine Marvels.
وَإِنَّ مِنۡهُمۡ لَفَرِيقٗا يَلۡوُۥنَ أَلۡسِنَتَهُم بِٱلۡكِتَٰبِ لِتَحۡسَبُوهُ مِنَ ٱلۡكِتَٰبِ وَمَا هُوَ مِنَ ٱلۡكِتَٰبِ وَيَقُولُونَ هُوَ مِنۡ عِندِ ٱللَّهِ وَمَا هُوَ مِنۡ عِندِ ٱللَّهِۖ وَيَقُولُونَ عَلَى ٱللَّهِ ٱلۡكَذِبَ وَهُمۡ يَعۡلَمُونَ
English translation: And indeed among them surely (is) a group they distort their tongues in (reciting) the Book so that you may think it (is) from the Book and not it (is) from the Book And they say It (is) from Allah But not it (is) from Allah And they say about Allah the lie while they know
Transliteration: wa-inna min'hum lafariqan yalwuna alsinatahum bil-kitabi litahsabuhu mina al-kitabi wama huwa mina al-kitabi wayaquluna huwa min indi al-lahi wama huwa min indi al-lahi wayaquluna ala al-lahi al-kadhiba wahum ya'lamuna
