Bihar al-Anwar 37:85
Ibn Abbas narrates:
The Messenger of Allah (s) was with Ali (a), Fatima (a), Hasan (a) and Husein (a) one day when he said:
'O Allah! You know that they are my family and they are the most honourable people in my eyes. O Allah! Love those who love them and hate those who hate them. Befriend their friends, antagonize those who antagonize them, and support those who support them. O Allah! Purify them from any uncleanliness; make them infallible and support them with the Holy Spirit.
The the Prophet (s) said:
It is as if I can see my daughter, Fatima (a), on the day of Judgment. She will be brought on a platform made of light. There will be seventy thousand angels to her right, seventy thousand angels to her left, seventy thousand angels in front of her, and seventy thousand angels behind her, and she will be leading the (female) believers of my nation to Paradise.
Every woman who prays five times a day, fasts in the month of Ramadhan, goes to Hajj, pays Zakat, obeys her husband, and accepts the wilayat of Ali (a) after me will enter Paradise with the intercession of my daughter. Fatima (a) is the master of all the world's women.
People asked, 'Is she the master of the women of her time?'
The Prophet (s) replied:
Maryam was the master of the women of her time. My daughter Fatima (a) is the master of all the world's women from the first to the last. Every time she stands in her Mihrab for prayers, seventy thousand high ranked angels come and say Salaam to her.
The angels call out to her, 'O Fatima! [Verily Allah has chosen you and purified you, and chosen you above all the women of the worlds] (3:42)' which is the same way the angels used to call Maryam.
Then the Prophet looked at Ali (a) and said:
O Ali! Fatima (a) is a piece of my flesh, she is the light of my eyes, and she is the apple of my heart.
That which saddens her saddens me and that which pleases her pleases me.
She is the first one from my family who will join me, so treat her with kindness after me.
As for Hasan (a) and Husein (a), they are my sons and my flowers. They are the masters of the youth of Paradise, so treat them like you would treat your eyes and ears.
Then the Prophet (s) raised his hands towards the sky and said:
'O Allah! I testify that I love those who love them. I hate those who hate them. I am at peace with those who are at peace with them. I fight those who fight them. I am the enemy of their enemies, and I am the friend of their friends.'
