Sayyiduna Abdullah bin Umar, may Allah be pleased with him, narrates: The Prophet Muhammad, peace and blessings be upon him, said: "I have been commanded to fight the people until they testify that there is no deity except Allah, and that I am the Messenger of Allah, and they establish prayer and pay zakat. When they do that, they will have protected their lives and wealth from me, except for the right of Islam, and their reckoning is with Allah the Exalted."
