so on one hand islam talks about hygiene being very important and on the other hand it is saying at one of the people in the marriage really is not obligated to do anything.
this does not add up, and i think is something that is not being stated properly. It is joint responsibility of husband and wife.
I think the saying is more so guys dont expect their wives to do all the work...on the other hand i dont think islam wants some contruction worker mazdoor to come home after 12 hours of backbreaking work, clean the house, cook meals and feed his wife.
What if someone of that kind exist and someone got that.
