Imam mubarakfuri رحمة الله عليه writes in explanation of the hadeeth (which can be seen in the picture):
لأن كمال الإيمان يوجب حسن الخلق و الإحسان إلى كافة الناس
و خياركم خياركم لنسائهم لأنهن محل الرحمة لضعفهن
(The) completion of imaan necessitates good behaviour and excellence towards all of mankind
(And in particular women) because they are in a position of needing mercy and kindness due to their fragility.
