"The dearest of my family to me is Fatimah"

It is narrated from Sayyiduna Usamah bin Zayd (may Allah be pleased with him) that I was in the mosque when Sayyiduna Abbas and Sayyiduna Ali (may Allah be pleased with them both) came to me and said: "O Usamah, seek permission for us (to meet) the Messenger of Allah (peace and blessings be upon him)." I went to the Prophet (peace and blessings be upon him) and said that Abbas and Ali (may Allah be pleased with them both) were asking permission. He (peace and blessings be upon him) asked: "Do you know what they have come for?" I said: "By Allah, I do not know." He (peace and blessings be upon him) said: "But I know; let them come in." The two of them came in and said: "O Messenger of Allah, we have come to ask you which of your family is most beloved to you?" He (peace and blessings be upon him) said: "Fatimah bint Muhammad is the most beloved to me of my family." They said: "O Messenger of Allah, we are not asking you about Fatimah (may Allah be pleased with her)." He (peace and blessings be upon him) said: "Then Usamah bin Zayd, upon whom Allah has bestowed favour and upon whom I have bestowed favour."
This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that Sayyiduna Zayd bin Harithah (may Allah be pleased with him) came to the Messenger of Allah (peace and blessings be upon him) with a complaint about Sayyidah Zaynab bint Jahsh (may Allah be pleased with her), and the Prophet (peace and blessings be upon him) said: "Keep your wife with you." Then this verse was revealed: [Surah al-Ahzab: 37] "And you were concealing within yourself that which Allah was to disclose."
