It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "The means for the people of the earth to be safe from disagreement is love of and attachment to Quraysh. Quraysh are the people of Allah and the custodians of Allah's blessings. So whenever any tribe of the Arabs opposes them, it will join the party of Iblis." This hadith has a sahih (authentic) chain, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abbas bin Abd al-Muttalib (may Allah be pleased with him) that he said: We would pass by a group of Quraysh while they were talking among themselves, and (on seeing us) they would stop their conversation. We mentioned this to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "What is the matter with people that when they see someone from my household, they break off their conversation?! By Allah, faith will not enter a man's heart until he loves them (my household) for the sake of Allah and because of my kinship." This hadith is also well known through the chain of Yazid bin Abi Ziyad, and since a supporting narration (shahid) for it has been found in this narration of Ibn Fudayl from al-A'mash, we have judged it to be authentic.

It is narrated from Sayyiduna Abbas bin Abd al-Muttalib (may Allah be pleased with him) that he said: I said: O Messenger of Allah, when the Quraysh meet one another, they meet with cheerfulness and joy, but when they meet us, their faces are changed. The narrator says: On hearing this, he (peace and blessings be upon him) became intensely angry and said: "By the One in whose Hand is the soul of Muhammad, faith will not enter a man's heart until he loves you for the sake of Allah and His Messenger."

It is narrated from Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The rulers (imams) will be from Quraysh. Their righteous will be the leaders of the righteous, and their sinners will be the leaders of the sinners. Each (subject and ruler) has a right, so give everyone who has a right his right. Even if I appoint over you a mutilated-nosed Abyssinian slave as leader, listen to him and obey, as long as he does not make any of you choose between his Islam and having his neck struck (that is, force him into disbelief). If he is made to choose between (abandoning) Islam and having his neck struck, let him offer his neck, for after (the loss of) his Islam there is no worth for him in either this world or the Hereafter." Mention of the virtues of the Muhajirun.
