I was wondering if it was problematic to believe that the Prophet had other daughters besides Fatima. I had learned as a Sunni that the prophet had other daughters besides Fatima, and I have recently learned that there is no evidence for it.
If you believe them to exist does that take away from the virtues of Bibi Fatima?

There are differences of opinions. Some shia scholars believe he had other daughters and some believe only Fatima (as).

It wouldn’t take away status just as the Imams had more children but it doesn’t take away virtues of the their child who is the next imam.
