I believe Fatima daughter of Mohammad is an equal level of Mohammad and Ali. Most Shiites see her 3rd best, but I believe Ahlulbayt (as) are of equal rank and of utmost submission and utmost possible praise for a creation to have.
Having said this, Women outnumber men in paradise, and even in the pre-covenant world, the feminine souls outnumber sincerity to God then males, that is why there are so many houral ayn who are pure souls that have no need of the trial of this world.
They are the greater of the two sexes, and woman manifest God's love and compassion more perfectly. He has made men to be regarding women to be ones who ought to uplift them, and raise them in confidence. He made the women more vulnerable to men and tried the women with being oppressed by men through history and God favors the oppressed over the oppressor, and God knew our souls lacked the patience to carry a child.
We are meant to protect women, uplift them, serve them, work for them, and women are meant to blessed flowers and the beautiful scent of God's love and be the adornment of humanity.
This is what the Quran teaches and hadiths teaches, and Quran when it says "and the male is not like the woman", it was in context, you been honored more then ever will know with Mariam and Mariam is not less then the Prophets in children Israel and in fact, she has the greater vessel and spiritually is their equal.
Fatima has been chosen with that name, because of the nature of the Originator, the nature of God that protects against the fire, and she is the heart of Islam, but most people don't realize.
As for Sarah, she is chosen as well.
But the fact is most of the pure souls that didn't need trial of this world, just as Prophets don't need trial of this world but come to help us, are women. They are houral Ayn. And most converts to Islam are women.
