Sahih al-Bukhari 7099Book 92, Hadith 50
حَدَّثَنَا عُثْمَانُ بْنُ الْهَيْثَمِ، حَدَّثَنَا عَوْفٌ، عَنِ الْحَسَنِ، عَنْ أَبِي بَكْرَةَ، قَالَ لَقَدْ نَفَعَنِي اللَّهُ بِكَلِمَةٍ أَيَّامَ الْجَمَلِ لَمَّا بَلَغَ النَّبِيَّ صلى الله عليه وسلم أَنَّ فَارِسًا مَلَّكُوا ابْنَةَ كِسْرَى قَالَ " لَنْ يُفْلِحَ قَوْمٌ وَلَّوْا أَمْرَهُمُ امْرَأَةً ".
During the battle of Al-Jamal, Allah benefited me with a Word (I heard from the Prophet). When the Prophet heard the news that the people of the Persia had made the daughter of Khosrau their Queen (ruler), he said, "Never will succeed such a nation as makes a woman their ruler."
