Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) narrates: After the Prophet (peace and blessings be upon him) passed away, if a boy came into the house, Sayyidah Fatimah (may Allah be pleased with her) (did not mind) even if there was no cloth on her head, but if a man came in, she would cover her head.
Al-Tabarani recorded it in al-Mu'jam al-Awsat. Its chain contains Amr bin Thabit al-Bakri, who is matruk (abandoned).
