Musnad Abu Ya'la al-Mawsili 150:451

Harun ibn Abdullah narrated to us, Abu Usamah narrated to us, Mujalid narrated to us, from Amir, from Masruq, from Aisha, who said: The Messenger of Allah (peace and blessings of Allah be upon him) entered upon me while I was weeping. He said, "What makes you weep?" I said, "Fatima insulted me." So he called for Fatima and said, "O Fatima, did you insult Aisha?" She said, "Yes, O Messenger of Allah." He said, "O Fatima, do you not love whom I love?" She said, "Yes." He said, "And do you not hate whom I hate?" She said, "Yes." He said, "Indeed, I love Aisha, so love her." Fatima said, "I will never say anything to Aisha that would hurt her, ever."
