Hadith 6:1043
Waki’ narrated to us, from Sufyan, from Hammad, from al-Sha’bi, who said: The mother of al-Harith ibn Abi Rabi’ah died while she was a Christian, and the companions of Muhammad, may Allah bless him and grant him peace, attended [her funeral].
حدثنا وكيع عن سفيان عن حماد عن الشعبي قال ماتت أم الحارث بن أبي ربيعة وهي نصرانية فشهدها أصحاب محمد صلى الله عليه وسلم
