Sayyiduna Abu Bakrah (may Allah be pleased with him) says: Allah benefited me through a word I heard from the Messenger of Allah (peace and blessings be upon him), after I had almost joined the people of the Camel to fight alongside them. When the news reached the Messenger of Allah (peace and blessings be upon him) that the people of Persia had made the daughter of Chosroes their ruler, he (peace and blessings be upon him) said: "A people who entrust their affairs to a woman will never succeed."
