Somewhat. Back in the day, when Islam was young and enemies abound, those who didn't want to see their idols dethroned in the city of Mecca and those who felt intimidated that God would send a prophet from Ishmael's pedigree (especially in the post-Jesus world) tried to do anything to damage or destroy the small community of believers. They made alliances, attempted to assassinate the Prophet Muhammad (numerous times), waged battle, slandered galore, and other tricks to do the deed. There were hypocrites among "the believers"; they would be Muslim by day and plotting maniacs by night, allying themselves with those who, on their own accord, chose enmity as their reception to Islam and its folk. They would change their "faith" for political expedience and promises in order to do some impolite things to a budding religious community. Their aim was not subtle.
In the aftermath of the passing of the Prophet, some Arab tribes (especially in the eastern half of the Arabian Peninsula) decided to edit out a core tenet of the faith and withhold their charitable requirement, and thus impale the very economic basis of a contiguous people and nation.
Now back to Afghanistan, a nation smitten in recent history by invasions, revolutions, extremists, and entrenched tribal logic. Anyone who has any awareness of the country will know that, like the so-called "honor killings" of India and Pakistan, this episode of apostasy "ruling" is informed not by Islamic sacred law or paradigms, but by a people poorly confronting their own ignorance and psychological traumas. Just like the destruction of the Buddhist statues in Afghanistan, which existed for centuries unmolested by the Muslim authorities that ruled the region (which once contained many centers of high learning, if one can imagine that), this Afghani fellow, a Muslim turned Christian, just may be another victim of the contemporary Muslim "funk" and, a lesser issue, may add to the misunderstanding of Islam and lend further credence to questionable theories of civilizations and their inevitable clashes.
