Musnad Ahmad 27:1785

Hajjaj narrated to us, Shareek narrated to us, from Uthman ibn Abi Zur'ah, from Muhajir al-Shami, from Ibn Umar, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever wears a garment of fame, Allah, Blessed and Exalted is He, will clothe him in a garment of humiliation on the Day of Resurrection." Shareek said: "And I have seen Muhajir and sat with him."
