(It is obligatory upon every) accountable (Muslim to perserve one’s faith in Islam and protect it against whatever invalidates, abolishes, and interrupts it, namely, apostasy “riddah”; we seek refuge with Allah, ta^ala, from it.) Blasphemy is the most grievous sin. It is the sin that Allah does not forgive for the one who dies on it, i.e., dies as a blasphemer, and He forgives whatever is less than that for whomever He wills.
