What did the Prophet Muhammad (saw) tell Fatima (peace be upon her) that made her weep and laugh alternately?
 Narrated `Aisha:                     Once Fatima came walking and her gait resembled the gait of the Prophet . The Prophet said, "Welcome, O my daughter!" Then he made her sit on his right or on his left side, and then he told her a secret and she started weeping. I asked her, "Why are you weeping?" He again told her a secret and she started laughing. I said, "I never saw happiness so near to sadness as I saw today." I asked her what the Prophet had told her. She said, "I would never disclose the secret of Allah's Apostle ." When the Prophet died, I asked her about it. She replied. "The Prophet said.) 'Every year Gabriel used to revise the Qur'an with me once only, but this year he has done so twice. I think this portends my death, and you will be the first of my family to follow me.' So I started weeping. Then he said. 'Don't you like to be the mistress of all the ladies of Paradise or the mistress of all the lady believers? So I laughed for that."
