It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whenever a nation fell into disagreement after its prophet, its people of falsehood prevailed over its people of truth."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abdullah bin Dinar (may Allah have mercy on him) except Musa bin Ubaydah, and no one narrated it from Musa except Abu Bakr bin Ayyash (may Allah have mercy on him); Mansur bin Abi Nuwayrah is alone in narrating it."
