Sayyidah Aishah (may Allah be pleased with her) said: I used to see the Messenger of Allah (peace and blessings be upon him) kissing Sayyidah Fatimah (may Allah be pleased with her), so I said: O Messenger of Allah, I see you doing something I did not see you doing before. He (peace and blessings be upon him) said to me: "O Humayra', on the night I was taken up to the heaven (the Mi'raj), I was admitted into Paradise. I stopped at one of the trees of Paradise; I did not see in Paradise any tree more beautiful than it, nor one with whiter leaves, nor one with finer fruit. I picked one of its fruits and ate it, and it became a drop of seed in my loins. When I came down to the earth, I went in to Sayyidah Khadijah (may Allah be pleased with her), and she conceived Fatimah. So whenever I long for the fragrance of Paradise, I smell the scent of Fatimah. O Humayra', Fatimah is not like the ordinary women of the children of Adam, nor does she suffer ailments as they do."
