Premediated murder in Saudi Arabia must have the following prerequisites: (1) an objective for the crime, (2) an instrument to commit the crime, and (3) criminal intent. To be criminally responsible, the offender must be a sane adult and not the victim's father. Murder by error occurs when criminal intent is absent, and the killing is deemed quasi-deliberate when an instrument is not used to do the killing. Capital punishment is prescribed for premeditated murder so as to implement the justice demanded in the Sharia. A sword or rifle is used for executions. Every sentence of capital punishment is reviewed up to the King before the execution is implemented. Where a murder is quasi-deliberate or by error, blood money is prescribed. This involves the offender paying the victim something of value, namely, a certain number of camels supplemented by gold or silver. Expiation (Kaffara) is prescribed as an opportunity for the Muslim offender who murders in error to purify himself. It is a punishment imposed to bring the Muslim back to God. It consists of the freeing of a believing slave, or if this is beyond an offender's means, a fast for two consecutive months is prescribed.
