Silsilah as-Sahihah 129 — How long should fighting continue?

Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "I have been commanded to fight the people until they say 'La ilaha illallah' (there is no deity worthy of worship except Allah). When they say 'La ilaha illallah', they will protect their wealth and lives from me, except for the right of Islam, and their reckoning will be with Allah the Exalted."
