Or worldly punishment anyway....
In the 30 cases where apostasy is mentioned in the Qur'an, there is not a single mention of a punishment for apostasy in this world.... and in chapter 4, a chapter revealed at Madina where muslims had their own government, in verse 137, talks of those who committ apostasy, then revert, the n committ apostasy, and so on, and makes no mention of a punishment by humans, and if the apostate is to be killed the first time, how are they to revert and apostasize over and over again? furthermore, there is an authentic hadeeth (saying) of Prophet Muhammad where a man accepts Islam and makes a pledge to Muhammad, then later comes and says, "O Prophet, cancel my pledge," and Muhammad refuses, so the next three days, every day, he comes back to cancel his pledge, then leaves Madinah, and Muhammad does nothing... also, the hadeeth people quote as being reason for killing apostates, ("whosoever leaveth his religion, kill him,") only has one narrator and is so vaguely worded that it could mean a Jew who converts to Islam is to be killed, which would obviously be bad from a muslim's point of view.... also, the other hadeeth people cite, which says, "there are only 3 cases in which a Muslim's blood may be shed, as retaliation for murder, as punishment for illegal sexual intercourse, and for leaving Islam and leaving the Muslims" may refer to those 'hypocrites' who were pretending to be Muslim to weaken islam after leaving, and to relay information as spies to those who wished to hurt Islam, and for those who "left the Muslims" meaning those who join ranks with the enemy... also, the ottoman empire abolished the death penalty for apostasy in 1844...also the hadeeth about leaving the muslims is contradicted by the hadeeth of a man who left islam and canceled his pledge...
