Islam and blasphemy
Blasphemy in Islam is any irreverent behavior toward holy personages, religious artifacts, customs, and beliefs that Muslims revere. The Quran and the hadith do not speak about blasphemy.
Jurists created the offence, and they made it part of Sharia.
Where Sharia pertains, the penalties for blasphemy can include fines, imprisonment, flogging, amputation, hanging, or beheading. Muslim clerics may call for the punishment of an alleged blasphemer by issuing a fatwā
