The Encyclopedia of Islam says: "In Fikh (jurisprudence), there is unanimity that the male apostate must be put to death."
This ruling has been accepted Islamic law for the last 1400 years. Established, historical Islamic theology and jurisprudence mandates the execution of apostates. Few Muslim scholars have ever challenged this definition. The majority of Islamic scholars support it. Various modern Muslims have objections against the death sentence but as Dog points out - it is they who are deviating from the judgment established by the depth and breadth of Islamic jurisprudence.There is no question that Islam mandates it, except from Muslims living in the West who are embarrassed by it and do their best to cover it up to try and make Islam more acceptable to naive, gullible and ignorant Westerners.
The Sirat Rasulallah provides details behind one of the names – Abdullah Sa’d.
Abdullah apostatized and Muhammad wanted him dead. Abdullah was one of Muhammad’s scribes and said that the reason he left Islam was because he was able to write his own words as the Quran with Muhammad’s approval. Once he realized the Quran was a sham he left Islam.[15] Later, when Muhammad’s knife was poised at his throat, he realized that Islam was true after all and rejoined the fold.
Tabari's whole job after the death of Big Mo was to go to all the tribes who had been forced to convert to Islam - and who now thought that because Big Mo was dead they no longer had to be Muslims - and kill them all.
Islam is, in my view - a giant puddle of vomited hatreds - Christians, Jews, dogs, women, gays, infidels, apostates, etc, etc - and the fact that modern Muslims and their Western supporters must wade through the puddle of vomit to pick out anything that might still be edible....well, I just shake my head as to why you would want to. And holding up that tiny kernel of humanity that you find in the vomit like "Aha! See! Islam is Goooooooood!" I will pat you on the head and smile because you're really excited about finding that edible piece amongst the vomit, but do not try to force it down my throat. You swallow what you want but stop forcing everyone else to swallow your vomit morsels.
