[Machine] From the ship of Abu Abd al-Rahman, the slave of the Prophet Muhammad ﷺ , it is narrated that the Prophet Muhammad ﷺ said, "The caliphate of prophethood will last for thirty years." Said Sa'id, "Abu Bakr's caliphate lasted for two years, Umar ibn al-Khattab's lasted for ten years, Uthman ibn Affan's lasted for twelve years, and Ali's lasted for six years." Al-Dhahabi removed it from the summary due to its weakness.
