My question is was hazrat qasim(a.s) married? What was his age? With whom was he married?
We connect him with Bibi Fatima Kubra (s.a) but heard that she's much elder than him and was already married, what's the truth?
If she was already married who's her husband? Why do people all over the world celebrate hazrat qasim (a.s) mehendi?
