What is the ruling on insulting the religion of the Jews and Christians?

All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

Allaah The Almighty Says (what means): {And do not insult those they invoke other than Allaah, lest they insult Allaah in enmity without knowledge. Thus We have made pleasing to every community their deeds. Then to their Lord is their return, and He will inform them about what they used to do.} [Quran 6:108]

 Al-Qurtubi said that the ruling of this verse applies at all times and in all situations. Whenever non-Muslims are strong and secure, and if it is feared that they might insult Islam, the Prophet, sallallaahu ‘alayhi wa sallam, or even Allaah The Almighty, it is impermissible to insult their crucifix, religion or churches. Moreover, it is impermissible to do anything that may lead them to insult Islam, the Prophet, sallallaahu ‘alayhi wa sallam, or Allaah The Almighty.

This is so even though it is permissible for experts to explain the falsehood and distortion of the books and creeds of non-Muslims so that people would thereby not believe that such religions are true. This is a recommended action, and may be obligatory for a sufficient number of Muslims. These experts should also refute the false allegations made against Islam.

We ask Allaah The Almighty to strengthen the status of Islam in the world, and to make people accept Islam.

Allaah Knows best.
