On the contrary, it is in full accord with the revealed Law—indeed, it is one of its very components. We merely call it “policy” because that is your usage, whereas in truth it is sound Sharʿī legislation. The Prophet (peace and blessings be upon him) detained people on mere suspicion and punished on suspicion when indications of wrongdoing became apparent. Thus, anyone who sets such suspects free, lets them go on their way, or merely makes them swear an oath while knowing their notoriety for spreading corruption on earth, is acting contrary to sound Sharʿī policy. Rather, those who fall under suspicion are to be disciplined, and claims that ordinary custom and common sense belie are not to be entertained.

Shaykh Taqī al-Dīn Ibn Taymiyyah said, regarding practitioners of sorcery and charlatanry: “The one who handles snakes, enters fire, and the like must be disciplined with taʿzīr.”

Taʿzīr is likewise imposed on anyone who belittles a Muslim by calling him “muslimānī,” on one who addresses a dhimmī as “ḥājj,” or on anyone who labels a mere visitor to graves and shrines a “pilgrim,” and the like.

If it becomes evident that a claimant lied in a manner that harmed the defendant, he is to be disciplined and held liable for whatever the defendant was unjustly made to pay, for his false claim directly caused that wrongful loss.
