It is narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "People follow Quraysh: the good among them follow the good of Quraysh, and the bad among them follow the bad of Quraysh."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu Hazim except Abd al-Aziz bin al-Muttalib, and no one from Abd al-Aziz except Ibrahim bin Sa'd; Ma'mar bin Bakkar is alone in narrating it, and this hadith is not narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) through any chain other than this one."
