Prophet sallallaho alaihi wasallam even said something like that to Hazrat Ali that “Faatimah is a part of me, and whatever hurts her hurts me.”
He also said to Hazrat Ali radhiyallaho anho that if you want to marry abu jehel's daughter then divorce my daughter.
Shia don't love ahle bayt, it is all they play drama. In one of their book, it says that when when the prophet sallallaho alaihi wasallam told to Hazrat Fatima radhiyallaho anha that your son will get shaheed, when she heard this she said I don't want such a cursed child (Naoozubillah). Hazrat Ali also said the same thing, as written in their book. I don't remember what is the name of that book, I think it's name is Qoomi or something like that.
