Wiladat Mola Ali:
The most agreed upon reference exists in the Sunni book, mustadrak al hakim, hadith number 6044. I am attaching image below from book.
Hakim Neishaburi writes down in his book, Mustadrak, Vol. 3, Hikmat 6044: “numerous and definite quotations narrate that Fatimah Bint Asad has delivered Imam Ali (PBUH) inside the Kaaba.”
