In categorizing offences and deciding punishments, judges are guided mainly by vaguely worded laws and general principles of Islamic jurisprudence on crimes and punishment which are subject to different interpretations by different Islamic jurists. For example, it is the judge who decides what constitutes apostasy. 'Abd al-Karim Mal al Allah, a Shi'a Muslim, was found guilty of apostasy and executed in 1992. It has been reported that he was told by the judge ''abandon your rejectionist beliefs or I will kill you''.
