Al-Jawab al-Sahih Liman Baddala Din al-Masih is a work authored by Shaykh al-Islam Ibn Taymiyyah in refutation of a treatise originating from Qubrus by a Christian monk called Paul of Antioch who attempted to argue for Christianity by both reason and revelation (i.e. using the Qur'an itself) and dismissing that the call of Islam is applicable to them, the Christians. Ibn Taymiyyah also intended this work as a general invitation to Christians to Islam, beyond the specific purpose for which it was mainly written.
