Islam and blasphemy

Blasphemy in Islam is impious utterance or action concerning God, Muhammad or anything considered sacred in Islam. The Quran admonishes blasphemy, but does not specify any worldly punishment for blasphemy. The hadiths, which are another source of Sharia, suggest various punishments for blasphemy, which may include death. However, it has been argued that the death penalty applies only to cases where there is treason involved that may seriously harm the Muslim community, especially during times of war. Various fiqhs (schools of jurisprudence) of Islam have different punishment for blasphemy, depending on whether blasphemer is Muslim or non-Muslim, man or woman. The punishment can be fines, imprisonment, flogging, amputation, hanging, or beheading.

Muslim clerics may call for the punishment of an alleged blasphemer by issuing a fatwā.

There are a number of surah in Qur'an relating to blasphemy, from which Quranic verses 5:33 and 33:57-61 have been most commonly used in Islamic history to justify and punish blasphemers. For example,

Those who annoy Allah and His Messenger - Allah has cursed them in this World and in the Hereafter, and has prepared for them a humiliating Punishment.

Truly, if the Hypocrites, and those in whose hearts is a disease, and those who stir up sedition in the City, desist not, We shall certainly stir thee up against them: Then will they not be able to stay in it as thy neighbours for any length of time: They shall have a curse on them: whenever they are found, they shall be seized and slain (without mercy).
