“They wish you would disbelieve as they disbelieved so you would be alike. So do not take from among them allies until they emigrate for the cause of Allah. But if they turn away, then seize them and kill them wherever you find them and take not from among them any ally or helper.” (Qur’an 4:89)
A hadith depicts Muhammad saying: “Whoever changed his Islamic religion, then kill him” (Bukhari 9.84.57). The death penalty for apostasy is part of Islamic law according to all the schools of Islamic jurisprudence.
This is still the position of all the schools of Islamic jurisprudence, both Sunni and Shi’ite. 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.”
Qaradawi also once famously said: “If they had gotten rid of the apostasy punishment, Islam wouldn’t exist today.”

Maintal (kath.net/ idea) An Afghan Christian (31) has been attacked in Maintal (near Frankfurt) by four Muslim Afghans. They are to have shouted “Allahu akbar” (Allah is great) and they wanted to kill him.

The attack occurred on the evening of 17 August. While getting on his bike, the Afghan Christian was outside his apartment, an Afghan tried to prevented him.

At the hospital, bruises on the shoulder, forearm and face were found on the Christian.
According to Dauth it was the third such attack on Afghan Christians. The situation is particularly difficult for him because he had converts [sic] from Islam to Christianity, “Who speaks openly about his faith as a convert to devout Muslims and does not hide his cross, is not safe in Germany.
“The Afghan Christian is still in the asylum procedure and has worked for a temporary employment agency. Three of the four attackers are housed, according to the victim in the refugee shelter in Maintal, in which he himself has worked as a translator. The fourth is allegedly living in Darmstadt.
As Dauth further said, other refugees from the Maintaler housing facility had warned the Afghan Christians of an attack. The Muslim Afghans had talked about it in advance….
