وَاِنَّ مِنْهُمْ لَفَرِیْقًا یَّلْوٗنَ اَلْسِنَتَهُمْ بِالْكِتٰبِ لِتَحْسَبُوْهُ مِنَ الْكِتٰبِ وَمَا هُوَ مِنَ الْكِتٰبِ وَیَقُوْلُوْنَ هُوَ مِنْ عِنْدِ اللّٰهِ وَمَا هُوَ مِنْ عِنْدِ اللّٰهِ وَیَقُوْلُوْنَ عَلَی اللّٰهِ الْكَذِبَ وَهُمْ یَعْلَمُوْنَ ۟

Wa inna minhum lafaree qany yalwoona alsinatahum bil Kitaabi litahsaboohu minal Kitaab, wa maa huwa minal Kitaabi wa yaqooloona huwa min 'indillaahi wa maa huwa min 'indillaahi wa yaqooloona 'alal laahil kaziba wa hum ya'lamoon

“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!”
