Sahih Bukhari Volume 5, Book 64, Hadith 4427

حَدَّثَنَا عُثْمَانُ بْنُ الْهَيْثَمِ، حَدَّثَنَا عَوْفٌ، عَنِ الْحَسَنِ، عَنْ أَبِي بَكْرَةَ، قَالَ لَقَدْ نَفَعَنِي اللَّهُ بِكَلِمَةٍ سَمِعْتُهَا مِنْ، رَسُولِ اللَّهِ صلى الله عليه وسلم أَيَّامَ الْجَمَلِ، بَعْدَ مَا كِدْتُ أَنْ أَلْحَقَ بِأَصْحَابِ الْجَمَلِ فَأُقَاتِلَ مَعَهُمْ قَالَ لَمَّا بَلَغَ رَسُولَ اللَّهِ صلى الله عليه وسلم أَنَّ أَهْلَ فَارِسَ قَدْ مَلَّكُوا عَلَيْهِمْ بِنْتَ كِسْرَى قَالَ ‏"‏ لَنْ يُفْلِحَ قَوْمٌ وَلَّوْا أَمْرَهُمُ امْرَأَةً ‏"‏‏.‏

Narrated By Abu Bakra : 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."
