question #3 Sahih al-Bukhari 3492, Book 61, Hadith 4 : Who was An-Nadr bin Kinana in relation to the Prophet Muhammad’s lineage?

I was told by the Rabiba (i.e. daughter of the wife of the Prophet) who, I think, was Zainab, that the
Prophet (forbade the utensils (of wine called) Ad-Dubba, Al-Hantam, Al-Muqaiyar and Al-Muzaffat. I
said to her, ‘Tell me as to which tribe the Prophet (ﷺ) belonged; was he from the tribe of Mudar?” She
replied, “He belonged to the tribe of Mudar and was from the offspring of An-Nadr bin Kinana. ”
