Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) narrated: "When the Messenger of Allah (peace and blessings be upon him) passed away, Sayyidah Fatimah (may Allah be pleased with her) would uncover her head when a boy came in (to the house), and when a (grown) man came in, she would cover it."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) only with this chain, and Ibrahim bin Sa'id is alone in narrating it."
