Volume: 005 / Book Number: 059 / Hadith Number: 709
During the days (of the battle) of Al-Jamal, Allah benefited me with a word I had heard from Allah's Apostle after I had been about to join the Companions of Al-Jamal (i.e. the camel) and fight along with them. When Allah's Apostle was informed that the Persians had crowned the daughter of Khosrau as their ruler, he said, "Such people as ruled by a lady will never be successful."
