"The punishment of those who wage war against Allah and His Messenger, and strive with might and main for mischief through the land is: execution, or crucifixion, or the cutting off of hands and feet from opposite sides, or exile from the land: that is their disgrace in this world, and a heavy punishment is theirs in the Hereafter, Except for those who return repenting before you apprehend them. And know that Allah is Forgiving and Merciful.
— Qur'an, Sura 5, ayat 33 & 34"
