Musnad Ahmad 28:470

Yazid ibn Harun narrated to us, al-Jurayri informed us, from Maymun ibn Ustad, from al-Sadafi, from Abdullah ibn Amr, from the Prophet (peace and blessings of Allah be upon him), who said: "Whoever among my nation dies while he is drinking wine, Allah will forbid him from drinking it in Paradise. And whoever among my nation dies while he is wearing gold, Allah will forbid him from wearing it in Paradise."
