wa'alaykumu salaam sister the hadith mentioned by yourself in the post says it all sister...the whole world can be turned upside down, the sun can stop rising, the seas can dry up...however the words of our Prophet sallallaahu 'alayhi wasallam can never be worng! So now, if it is as clear as day that a nation under the leadership of women will never prosper, i really do not see the need for a discussion on it. As for the role of mother/wife/home maker, it is only natural that a woman takes on that role since the role of the man is as breadwinner/protector etc.....This is of course in an ideal Muslim home where each compliments the other perfectly! Sadly nowadays each person is more worried about demanding their rights than fulfilling them. May Allah ta'ala guide us on the path leading to His pleasure.
