Amr bin Uthman bin Affan narrates from his father (Sayyiduna Uthman, may Allah be pleased with him) that he said to me: O my son, if you are ever made governor and put in charge of any affair of the people, then honor and respect Quraysh, for I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever humiliates Quraysh, Allah, Mighty and Majestic, will disgrace him."

Muhammad bin Sa'd bin Abi Waqqas narrates from his father that the Messenger of Allah (peace and blessings be upon him) said: "Whoever intends the disgrace of Quraysh, Allah will humiliate and abase him." This hadith has also been narrated by Imam al-Layth bin Sa'd, and it is among the finest hadiths that senior imams narrated from those junior to them.

It is narrated from Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) that he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever intends the disgrace and humiliation of Quraysh, Allah, Mighty and Majestic, will abase and disgrace him." In this narration, Yusuf bin Abi Aqil is without doubt Yusuf bin al-Hakam, and it is authentically established from the Messenger of Allah (peace and blessings be upon him) that a son is not held responsible for his father's crime.

Hamzah bin Abi Sa'id al-Khudri narrates from his father (Sayyiduna Abu Sa'id al-Khudri, may Allah be pleased with him) that he said: I heard the Messenger of Allah (peace and blessings be upon him) say on the pulpit: "What is the matter with people who say that my kinship will not benefit? Of course it will, by Allah! My kinship is connected in both this world and the Hereafter. And, O people, I will be your forerunner (the one who receives you) at the Pond of Kawthar. When I am there, some men will stand up; one of them will say: 'O Messenger of Allah, I am so-and-so,' and another will say: 'O Messenger of Allah, I am so-and-so.' Then I will say: 'I have recognized you, but after me you introduced new things (into the religion) and turned back on your heels (to your former religion).'" This hadith has a sahih (authentic) chain, but the two Shaykhs did not record it.
