Is it obligatory to disclose the identity of a thief who has repented and promised not to repeat his act, and who has requested that his matter not be revealed, while there are other accused individuals who wish to know the real thief?

Concealing a Muslim's misdeed is recommended for one who is not known for corruption and has committed a slip. However, for someone known for evil and corruption, concealing their misdeed is not recommended. Instead, their matter should be reported to the responsible authorities to stop their evil, because concealing it would embolden them and others like them to commit evil and harm people.

Al-San'ani said: The hadith "Whoever conceals a Muslim, Allah will conceal him" applies to those not known for corruption. As for those who are known for it, concealing their misdeeds is not recommended; rather, their matter should be reported to those in authority.

If one sees someone committing a sin, the obligation is to promptly denounce and prevent it, if capable.

If one sees someone stealing another's property, it appears obligatory to inform the owner of the property; otherwise, one would be assisting the thief.

The Permanent Committee stated that one must first advise the thief. If he does not desist, then it is obligatory to inform the competent authorities to restore the right to its owner and deter the wrongdoer.

Accordingly, if the thief is known for evil and corruption, his misdeed should not be concealed; rather, his matter should be reported to the competent authorities. If he is not known for such, then there is no harm in concealing his misdeed after the theft has occurred. In all cases, the stolen items must be returned to their owners.
