The inviolability of the Muslim

On the authority of Ibn Umar (may Allah be pleased with him and with his father), that the Messenger of Allah (may Allah bless him and grant him peace) said: "I have been commanded to fight the people until they testify that there is none worthy of worship but Allah and that Muhammad is the Messenger of Allah, and they establish the prayer and pay the zakat. When they do that, their blood and their property are protected from me, except by the right of Islam, and their reckoning is with Allah."

Related by al-Bukhari and Muslim. The substance of this hadith is with both, but only al-Bukhari relates the words “except by the right of Islam”.
