Story of Kawlah bint Azwar is from Futuhatu sham... There are lot of controversies over the credibility of the book. Still its not proved (Allah knows the best). There is no Quran verses or hadith about her... bcz she lived after ages of Prophets. And the first woman military college in UAE was named after her. This is just a story.... Not a rule or principle against islam.... So we can't get exact and full evidence on that❤️❤️❤️
