Qur’an (6:93) “Who can be more wicked than one who inventeth a lie against Allah?” If the death penalty is prescribed for lesser crime, then it stands to reason that it should be imposed for the most “wicked”.
Qur’an (33:57) “Lo! those who malign Allah and His messenger, Allah hath cursed them in this world and the Hereafter, and hath prepared for them the doom of the disdained”
Qur’an (33:61) “Accursed, they will be seized wherever found and slain with a (fierce) slaughter.”
