It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) 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 none worthy of worship except Allah). Then, when they say it, they have protected their blood and their wealth from me, except by the right of it (the testimony), and their (inner) reckoning is with Allah."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Mubarak bin Fadalah except Umar bin Sahl al-Mazini, and Ishaq bin al-Dayf is alone in narrating it."
