Sulayman bin Abi Sulayman narrates from his mother Umm Sulayman (both of them are thiqah (trustworthy)) that she said: I went to Sayyidah Aishah Siddiqah (may Allah be pleased with her), the wife of the Prophet (peace and blessings be upon him), and asked her about the meat of sacrifices, since the Prophet (peace and blessings be upon him) used to forbid it and then he gave a concession for it. Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) returned from a journey, and Sayyidah Fatimah (may Allah be pleased with her) brought him meat from her sacrifice. Sayyiduna Ali (may Allah be pleased with him) said: Did the Prophet (peace and blessings be upon him) not forbid this? Sayyidah Fatimah (may Allah be pleased with her) said: The Prophet (peace and blessings be upon him) has given permission for it. (Allamah al-Haythami says:) I say: (The hadith) from Sayyidah Aishah (may Allah be pleased with her) is reported in the "Sahih", but it does not contain the incident of Sayyidah Fatimah (may Allah be pleased with her); that is why Imam Ahmad recorded this report in the Musnad of Ahmad, in the section of the Musnad of Fatimah.
Ahmad and al-Tabarani in al-Mu'jam al-Awsat recorded it, and he says: The woman named Umm Sulayman narrated no hadith other than this one. (Allamah al-Haythami says:) I say: This woman has been declared trustworthy, as is reported in the "Musnad", and the remaining narrators of Ahmad are thiqat (trustworthy).
