“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)
أَتَيْتُ رَسُولَ اللهِ ﷺ فِي وَفْدٍ لَا يَرَوْنَ أَنِّي أَفْضَلُهُمْ فَقُلْتُ يَا رَسُولَ اللهِ إِنَّا نَزْعُمُ أَنَّكُمْ مِنَّا قَالَ نَحْنُ بَنُو النَّضْرِ بْنُ كِنَانَةَ لَا نَقْفُو أُمَّنَا وَلَا نَنْتَفِي مِنْ أَبِينَا قَالَ فَكَانَ الْأَشْعَثُ يَقُولُ لَا أُوتَى بِرَجُلٍ نَفَى قُرَيْشًا مِنَ النَّضْرِ بْنِ كِنَانَةَ إِلَّا جَلَدْتُهُ الْحَدَّ
