Burning people alive as punishment couldn't be more Islamic.
Muhammad burned people alive for nothing more than not showing up for compulsory prayer.Bukhari Book #41, Hadith #602: Narrated Abu Huraira:
The Prophet said, "No doubt, I intended to order somebody to pronounce the Iqama of the (compulsory congregational) prayer and then
I would go to the houses of those who do not attend the prayer and burn their houses over them."
Muslim Book #004, Hadith #1373: 'Abdullah reported
Allah's Messenger (may peace be upon him)
as saying about people who are absent from Jumu'a prayer:
I intend that I should command a person to lead people in prayer, and then
burn those persons who absent themselves from Jumu'a prayer in their houses.http://www.searchtruth.com/searchHadith.php?keyword=burn+house&translator=2&search=1&book=&start=0&records_display=10&search_word=allBukhari Book #11, Hadith #626: Narrated Abu Huraira: The Prophet said, "No prayer is harder for the hypocrites than the Fajr and the 'Isha' prayers and if they knew the reward for these prayers at their respective times, they would certainly present themselves (in the mosques) even if they had to crawl." The Prophet added, "Certainly I decided to order the Mu'adh-dhin (call-maker) to pronounce Iqama and order a man to lead the prayer and
then take a fire flame to burn all those who had not left their houses so far for the prayer along with their houses."

AP - December 06, 2006 MOGADISHU, Somalia - "
Residents of a southern Somalia town who do not pray five times a day will be beheaded, an Islamic courts official said Wednesday, adding the edict will be implemented in three days."
