Muhammad commanded: “Whoever changed his Islamic religion, then kill him” (Bukhari 9.84.57).
Sheikh Yusuf al-Qaradawi, the most renowned and prominent Muslim cleric in the world, has stated: “The Muslim jurists are unanimous that apostates must be punished, yet they differ as to determining the kind of punishment to be inflicted upon them. The majority of them, including the four main schools of jurisprudence (Hanafi, Maliki, Shafi`i, and Hanbali) as well as the other four schools of jurisprudence (the four Shiite schools of Az-Zaidiyyah, Al-Ithna-`ashriyyah, Al-Ja`fariyyah, and Az-Zaheriyyah) agree that apostates must be executed.” There is only disagreement over whether the law applies only to men, or to women also – some authorities hold that apostate women should not be killed, but only imprisoned in their houses until death.
“A Christian Convert, on the Run in Afghanistan,” by Azam Ahmed, New York Times, June 21, 2014:
KABUL, Afghanistan — In a dank basement on the outskirts of Kabul, Josef read his worn blue Bible by the light of a propane lantern, as he had done for weeks since he fled from his family in Pakistan.
His few worldly possessions sat nearby in the 10-by-10-foot room of stone and crumbling brown earth. He keeps a wooden cross with a passage from the Sermon on the Mount written on it, a carton of Esse cigarettes, and a thin plastic folder containing records of his conversion to Christianity.
The documents are the reason he is hiding for his life. On paper, Afghan law protects freedom of religion, but the reality here and in some other Muslim countries is that renouncing Islam is a capital offense.
Josef’s brother-in-law Ibrahim arrived in Kabul recently, leaving behind his family and business in Pakistan, to hunt down the apostate and kill him. Reached by telephone, Ibrahim, who uses only one name, offered a reporter for The New York Times $20,000 to tell him where Josef was hiding.
“If I find him, once we are done with him, I will kill his son as well, because his son is a bastard,” Ibrahim said, referring to Josef’s 3-year-old child. “He is not from a Muslim father.”
For Josef, 32, who asked to be identified only by his Christian name to protect his wife and young child, the path to Christianity was only one segment on a much longer journey, a year of wandering that took him through Turkey, Greece, Italy and Germany, seeking refuge from Afghanistan’s violence.
But at each stop he found misfortune. He was detained in Greece and deported from Germany, and he lived on the streets in Italy before he truly understood that there would be no happy ending in Europe, where his application for asylum has gone nowhere. He voluntarily left Italy for Pakistan to be with his wife and son, but that is no longer an option.
Neither is reverting to Islam. “I inherited my faith, but I saw so many things that made me discard my religious beliefs,” Josef said. “Even if I get killed, I won’t convert back.”
In official eyes here, there are no Afghan Christians. The few Afghans who practice the faith do so in private for fear of persecution, attending one of a handful of underground churches that are believed to be operating in the country. Expatriates use chapels on embassy grounds, but those are effectively inaccessible to Afghans.
Only a few Afghan converts have surfaced in the past decade, and the government has typically dealt with them swiftly and silently: They are asked to recant, and if they refuse, they are expelled, usually to India, where an Afghan church flourishes in New Delhi….
