Where Sharia pertains, the penalties for blasphemy can include fines, imprisonment, flogging, amputation, hanging, or beheading.
Sharia comes mostly from the Qur'an. (no expert)
Also, this is not the first time something like this happens and usually blasphemy is one big reason why they do it. If it's not, that would be strange but I obviously have considered that I might be wrong.
