“Only her nephew, Abdullah ibn Ja‘far, narrated from her.”

However, I found for her a strong corroborating route. Abdullah, son of Imam Ahmad, said (4/332):

Muhammad ibn ‘Abbad al-Makki narrated to us: Abu Sa‘id—the freedman of Banu Hashim—narrated to us: Abdullah ibn Ja‘far narrated from Umm Bakr, and Ja‘far from Ubayd Allah ibn Abi Rafi‘, with the same report, except that he said shijna (“a branch”) in place of bud‘a (“a part”). The rest is exactly the same.

This is a sound chain of transmission. This Ja‘far is Ja‘far ibn Muhammad ibn ‘Ali ibn al-Husayn, Abu Abdullah al-Sadiq, the imam and jurist. He is trustworthy and among Muslim’s narrators, so he constitutes a strong corroboration. The remaining narrators in the chain—apart from Umm Bakr—are trustworthy narrators used by Muslim. Muhammad ibn ‘Abbad is Ibn al-Zuburqan al-Makki.

Al-Bukhari recorded the hadith in “Virtues of the Companions” (11/84, Fath), and al-Nasa’i in “al-Khasa’is” (p. 25), through Ibn Abi Mulaykah, from al-Miswar ibn Makhramah, in an abbreviated form:

“Fatimah is a part of me; whoever angers her angers me.”

Note: Al-Haythami did not come across the hadith in Musnad Ahmad, and therefore said in al-Majma‘ (9/203): “Al-Tabarani narrated it, and its chain includes Umm Bakr bint al-Miswar. No one has criticized or declared her trustworthy, while the rest of its narrators have been declared trustworthy!”

I say: Consequently, he missed this strong corroborating route. Allah is the One who grants success.

Al-Tabarani narrated it in al-Awsat (no. 328/2): Ahmad ibn Rushdayn narrated to us: Ahmad ibn Salih narrated to us: Abdullah ibn Wahb narrated to us: ‘Amr ibn al-Harith informed me from Ayyub ibn Musa that Yazid ibn ‘Abd al-Muzani narrated to him from his father, in a report traced back to the Prophet, and said:
