Hadith

On the authority of Ibn Masood (may Allah be pleased with him) who said:

The Messenger of Allah (peace and blessings of Allah be upon him) said,

“It is not permissible to spill the blood of a Muslim except in three [instances]:

The married person who commits adultery,

A life for a life,

And the one who forsakes his religion and separates from the community.”

It was related by al-Bukhari and Muslim.
