Sayyiduna al-Ash'ath bin Qays (may Allah be pleased with him) said: We came to the Prophet (peace and blessings be upon him) in a delegation from Kindah, and they did not regard me as better than them. I said: O Messenger of Allah! We claim that you are from us. He (peace and blessings be upon him) said: "No. We are Banu al-Nadr bin Kinanah; we do not trace our lineage through our mother, nor do we disown our father." Sayyiduna al-Ash'ath bin Qays (may Allah be pleased with him) said: O Prophet of Allah! I will not hear anyone separate Quraysh from Kinanah except that I will flog him.
