“I came to the Messenger of Allah ﷺ with a delegation from Kindah, and they thought that I was the best of them. I said: 'O Messenger of Allah ﷺ are you not from among us?' He said: 'We are the tribe of Banu Nadr bin Kinanah, and we do not attribute ourselves to our mother and we do not deny our forefathers.'”He said: “Ash'ath bin Qais used to say: 'If any man is brought to me who suggests that a man from Quraish does not belong to Nadr bin Kinanah, I would carry out the legal punishment (for slander) on him.'” (Using translation from Ibn Mājah 2612)
أَتَيْنَا النَّبِيَّ ﷺ فِي رَهْطٍ مِنْ كِنْدَةَ لَا يَرَوْنِي بِأَفْضَلِهِمْ فَقُلْتُ يَا رَسُولَ اللهِ إِنَّا نَزْعُمُ أَنَّكَ مِنَّا قَالَ «لَا نَحْنُ بَنُو النَّضْرِ بْنِ كِنَانَةَ لَا نَقْفُوا أُمَّنَا وَلَا نَنْتَفِي مِنْ أَبِينَا» قَالَ الْأَشْعَثُ بْنُ قَيْسٍ يَا نَبِيَّ اللهِ لَا أَسْمَعُ أَحَدًا نَفَى قُرَيْشًا مِنْ كِنَانَةَ إِلَّا جَلَدْتُهُ
