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."
لَقَدْ نَفَعَنِي اللَّهُ بِكَلِمَةٍ أَيَّامَ الْجَمَلِ لَمَّا بَلَغَ النَّبِيَّ ﷺ أَنَّ فَارِسًا مَلَّكُوا ابْنَةَ كِسْرَى قَالَ لَنْ يُفْلِحَ قَوْمٌ وَلَّوْا أَمْرَهُمُ امْرَأَةً
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 Messenger of Allah ﷺ 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."
لَقَدْ نَفَعَنِي اللَّهُ بِكَلِمَةٍ سَمِعْتُهَا مِنْ رَسُولِ اللَّهِ ﷺ أَيَّامَ الْجَمَلِ بَعْدَ مَا كِدْتُ أَنْ أَلْحَقَ بِأَصْحَابِ الْجَمَلِ فَأُقَاتِلَ مَعَهُمْ قَالَ لَمَّا بَلَغَ رَسُولَ اللَّهِ ﷺ أَنَّ أَهْلَ فَارِسَ قَدْ مَلَّكُوا عَلَيْهِمْ بِنْتَ كِسْرَى قَالَ لَنْ يُفْلِحَ قَوْمٌ وَلَّوْا أَمْرَهُمُ امْرَأَةً
