It is narrated from Amr bin Shu'ayb (may Allah have mercy on him) that he went to visit Sayyidah Zaynab bint Abi Salamah (may Allah be pleased with her), and she told him that the Messenger of Allah (peace and blessings be upon him) was at the home of the Mother of the Believers, Sayyidah Umm Salamah (may Allah be pleased with her): "He (peace and blessings be upon him) took up Sayyiduna Hasan (may Allah be pleased with him) on one side and Sayyiduna Husayn (may Allah be pleased with him) on the other side, and Sayyidah Fatimah (may Allah be pleased with her) was in his (peace and blessings be upon him) lap." Then he (peace and blessings be upon him) said: "O people of the household! May the mercy of Allah and His blessings be upon you. Indeed, He is Praiseworthy, Glorious."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyidah Zaynab bint Abi Salamah (may Allah be pleased with her) only with this chain, and Ibn Lahi'ah (may Allah have mercy on him) is alone in narrating it."
