Sayyidah Aishah (may Allah be pleased with her) said: Sayyidah Fatimah (may Allah be pleased with her) came walking, her gait as if it were like the gait of the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Welcome, my daughter." He seated her on his right or on his left, then said something to her in a whisper, and she wept. I said to her: The Messenger of Allah (peace and blessings be upon him) singled you out for his words, and then you weep? Then he (peace and blessings be upon him) whispered to her again, and she laughed. I said: I have never seen, as I have today, joy so close to grief. I asked her what he (peace and blessings be upon him) had said, and she said: I cannot disclose the secret of the Messenger of Allah (peace and blessings be upon him). Then, when he (peace and blessings be upon him) passed away, I asked again, and she said: He (peace and blessings be upon him) whispered to me and said: "Jibril used to review the Qur'an with me once every year, and this year he has reviewed it twice, so I think my time of death has come. And you will be the first of my household to join me, and what an excellent forerunner I am for you." So I wept at that. Then he (peace and blessings be upon him) said: "Are you not pleased to be the leader of the women of the Ummah, or of the Muslim women?" So I laughed at that.
