Q 2: What
is the ruling in Islam on a Muslim who reads the Injil (Gospel) and swears by it?
It is impermissible for a Muslim to read the Injil, for it is distorted, whereas the Qur'an supersedes the undistorted parts. However, there is an exception for reading the Injil when a person needs to read it (Part No. 23; Page No. 58) to refute the arguments of the People of the Book, but this is only restricted to scholars. Moreover, it is impermissible to swear by the Injil in its present condition, for some of it is distorted and changed, while these distortions are not of Allah's (revealed) Words (Glorified and Exalted be He).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
