“The Messenger of Allah said: ‘Whoever fasts one day in the cause of Allah, Allah will separate between his face and the fire by (a distance of) seventy autumns in return for that day.”‘
The Messenger of Allah said: “It is not permissible to shed the blood of a Muslim except in three cases: An adulterer who had been married, who should be stoned to death; a man who killed another man intentionally, who should be killed; and a man who left Islam and waged war against Allah, the Might and Sublime, and His Messenger, who should be killed, or crucified, or banished from the land.”
