It’s noted Imam Ali A.S & Fatima Zahra A.S had 5 Children together but did they have a Daughter named Sukayna?
I’m asking based off these 3 sources referring to Her as their Daughter

Mustadrak Safeenatul Bihar by al-Namazi volume 5 page 90

Wasa’il al-Shia by Hurr al-Aamili volume 14 page 168

and Bihar al anwar volume 45 page 104

I would love to know your opinion on this. There is also a shrine for Her in Damascus so she obviously existed & was the daughter of Imam Ali A.S the question is who was her mother

Yes he did have a daughter by name of sukayna but not from Lady Fatima (a)
