What about the Sunni Fiqh?

The Sunni fiqh is also in agreement with the views mentioned above on the punishment for apostasy. Soon after the Prophet's death, the Sunni caliphate started a widespread campaign of fighting some tribes in the interior of the Arabian Peninsula. The justification used by the caliphate was that the tribes had turned away from Islam; they had become murtad.

Even historians describe it as "waq`atu 'r-ridda -- the event of apostasy". Although we do not agree with the accusation leveled against some of those who were killed as "apostates,"18 but the justification presented by the caliphate shows that the Sunnis also agree with the Sh`iah fiqh on punishment for those who become murtad.

The Sunni author of the authoritative al-Fiqh `ala 'l-Madhāhibi 'l-Arba`ah writes, "The four (Sunni) Imams agree that it is obligatory to kill a person whose apostasy against Islam is proven."19 The Sunni jurists, however, do not differentiate neither between the fitri and the milli apostate, nor between male and female apostate.20
