Sayyiduna Abu Hurayrah (may Allah be pleased with him) says that the People of the Book used to recite the Torah in Hebrew and explain it in Arabic to the Muslims. The Messenger of Allah (peace and blessings be upon him) said: "Neither affirm them nor deny them; rather say: 'Say: We believe in Allah and in what has been sent down to us' [Surah al-Baqarah: 136], to the end of the verse."
