Assalaamualaykum. How would I respond to someone who is asking why women must be in the back during salat, or why women can't be imams in a mixed congregation?
There are so many reasons for this but what I know is that each creature is created for certain purpose like a women can give birth to a child but a man is not having that system so if we ask why men can not give birth to child , will have no use.
It is not that women have to be at the back during salat , she can be on the side also after putting partition in the prayer area .
I think It is clear from above example that why women can not be imam.
