Salam o Rahmat
Why does the Quran say "men" should be breadwinners and mainatiners of the family?
Some (as G.A. Pawez or Paigham Mustafa) say because of maternity/pregnancy of women and division of labour, men should do this task. But I see no explicit verse about the division of labor in the Quran.
Man/male must be the maintainer of his women, and these women can be his single sister or his barren wife etc, therefore this responsibilty cannot relate to the maternity or pregnancy of those women,
1- so what is the reason that maintaining of the family is the primary responsibility of Men?
2- And What is the responsibilty and role of women when men are the maintainers?
(I agree with this decree of the Holy Quran but i want to learn the logic behind this decree)
