What is the ruling on ridiculing Din (religion) of Islam and religious people?
Holding Din and religious people up to ridicule is Riddah (apostasy) that takes the one who does it out of the fold of Islam. Allah (Exalted be He) says,
Say: "Was it at Allâh (عز وجل), and His Ayât (proofs, evidence, verses, lessons, signs, revelations) and His Messenger (صلى الله عليه وسلم) that you were mocking?"
Make no excuse; you disbelieved after you had believed.
