Rabi'ah bin Najid (may Allah have mercy on him) says: I heard Sayyiduna Ali (may Allah be pleased with him) saying: "I have been commanded to fight the oath-breakers, those who deviate from the truth (the unjust), and those who go out of the religion."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Rabi'ah bin Najid except Salamah; his son is alone in narrating it."
