The Holy Prophet (s.a.w.a.) said, ‘When I was raised to the skies Jibrail guided me to Paradise with his hand. I was offered a date which I ate. It was transformed into semen in my loins. I then descended on the earth and lived with Khadija. Then she became pregnant with Fatimah (s.a.). Therefore Fatimah is a human Hoori. Whenever I wish to smell the fragrance of Paradise, I smell the fragrance of my daughter, Fatimah.’
