Egyptian Shaykh Muhammad Hassan, who is one of the most popular and well-known Islamic clerics in Egypt and even throughout the Islamic world (there is even a campaign in Egypt to try to get him to run for president), emphasizes in this video that apostates from Islam must be killed.
He argues, interestingly, that this does not conflict with the principle of no compulsion in religion, because no one is forced to enter Islam (or so he says). However, after they choose to enter Islam, they cannot be allowed to leave it.
