"There are two cases in Islam where the shedding of blood is permissible by Allah (swt), Blessed and Exalted, but no one will judge regarding them until Allah (swt), the Almighty and Majestic, sends forth our Qa'im (the Mahdi (as)) from among the Ahlulbayt. When Allah (swt) sends forth our Qa'im (as), he will judge them according to Allah’s (swt) command: the adulterer who is married will be stoned, and the one who withholds Zakat will have his neck struck (executed)."
