Here's an answer about apostasy from Williams which was posted a little while ago.
In sharia law, what is the penalty for apostasy? And, if we are all born Muslims, is not everyone other than Muslims an apostate?
Answered within the Muslim worldview by Shaheed Williams
Allah, or God in English, created human beings to worship Him alone and instilled within them an inclination towards doing that.
"And I did not create Jinn and men, except that they should worship Me alone." (51:56) "And remain steadfast on the pure religion, the faith with which Allah created mankind. There is no alteration in the religion of Allah." (30:30)
Prophet Muhammad said, "Every infant is born with an innate disposition (towards knowing and worshiping their Creator alone), but it is his parents who make him a Jew, or a Christian or a Magian." (Reported by Bukhari and Muslim)
So even though everyone is designed and programmed to be Muslims, they may not be raised as such, depending upon outside influences. This is different from apostasy.
An apostate is someone who leaves the religion of Islam for another religion. One is considered an apostate if he does this while being sane, and of his own free-will, without being forced.
The punishment for apostasy is similar to treason in most countries. The ruling of the apostate is that he is given an opportunity for three days to repent and return to Islam and he is encouraged intensely to do so. This is done by trying to dispel any doubts or misconceptions that he may have about Islam, making sure that he understands his decision. If he returns to Islam, he will be left alone, and if not, he is killed with the sword.
Prophet Muhammad said, "Whoever changes his religion (away from Islam), then kill him." (Reported by Bukhari)
If the apostate is killed, he is not washed (in Islamic ritual manner), prayed over (the Islamic funeral prayer) or buried in the cemeteries of the Muslims. He is not inherited from and whatever he left of wealth belongs to the Islamic State and should be used for the general benefit of the Muslims.
The purpose of performing capital punishment upon the apostate is to deter the remainder of society from repeating such an action. And of course this is to be done in a land in which Islamic Sharee'ah is established.
It is well known that in Madinah there existed a number of Jewish tribes and that some of the first protectors of the Muslims were the Abyssinians, who were Christians. Muslims also preserved the places of worship and the lives of the Christians and Jews in Muslim controlled Palestine and Spain. Had it been that every non-Muslim was considered an apostate, these events would never have happened.
Get a load of some of the claims, like: "everyone is designed and programmed to be Muslims." If you are programmed by Allah there is no such thing a freewill. If all people are programmed to be Muslims then how do you explain the "first" Jew or Christian? They were on the scene long before Muslims. Why didn't god programming them as Muslims? And what kind of ineffective programmer is Allah if "outside Influences" can easily make non-Muslims and defeat god that easily?
Leaving that aside, Williams justifies killing the apostate because Muhammad (may his name be damned) said "kill him" by the sword. Apparently, killing an apostate "spares" society from such an egregious action. Egregious how? Williams doesn't say how apostasy harms society. However, he does tell us that the Muslim state receives the assets of the executed apostate. Typical.
Here's the funny thing, Williams is a Christian apostate. If a Christian state currently executed apostates like Sharia mandates presently, Williams would not be here today as a columnist for "The God Contention." The irony!
Williams not only demonstrates the pure evil of authoritarianism, but also demonstrates that church and state must always necessarily remain separate if apostasy is tantamount to the punishment of "treason." Murdering someone because they have left their religion behind, for whatever reason, is completely antithetical to freedom of conscience and look how causally Williams endorses murder!
