[4] The classical Islamic jurisprudence typically divided the subject matter of law into four "quarters", that is rituals, sales, marriage, and injuries.
Examples of the second sub-category include false testimony, loaning money or any property to another person for interest in addition to principal, any acts that threaten or damage the public order or Muslim community or Islam.
The sixteenth-century Egyptian jurist Ibn Nujaym said that taʿzīr could consist of lashing, slapping, rubbing the ears, a stern telling-off, disparagement short of slander, or an angry look from the judge.
[20][33][34] All four schools of fiqh (Madhhab), namely Hanafi, Maliki, Shafii and Hanbali, permit the death penalty at the discretion of the state or Qadi, for certain Tazir offenses if it is proven by at two least witnesses or a self confession.
Tazir crimes in Brunei now include offenses such as failing to perform Friday prayers by anyone above 15 years old, any Muslim disrespecting the month of Ramadan, and khalwat (dating or any form of close proximity between unrelated members of opposite sex).
These Tazir laws allow prosecution of offenses such as illicit kissing, failing to wear proper head dress such as hejab, and making critical statements against judges and members of the Council of Guardians.
