If you see a man cursing the religion, do you declare him a disbeliever outwardly, or do you testify against him in court, or do you remain silent about it?

Question:
This questioner says: If I see a man cursing the religion, do I declare him a disbeliever outwardly, or do I testify against him in court, or do I remain silent about it?

Answer:
You must disapprove of him. When 'Awf ibn Malik saw the hypocrites speak about the Messenger and the believers, he disapproved of them and went to inform the Messenger (peace and blessings be upon him). So first, you should advise him; perhaps he is ignorant, or perhaps he is being tested. Advise him, command him to repent to Allah and not to return to such a thing. If he persists, then you must refer his case to the authorities. Yes.
