Musnad Ahmad 33:1176

Bahz narrated to us, Muthanna ibn Sa'id narrated to us, Talha ibn Nafi' narrated to us, from Jabir ibn Abdullah, that the Prophet of Allah (peace and blessings of Allah be upon him) took his hand to his house. When he arrived, he said: "Is there any lunch - or dinner?" Talha was uncertain. He said: So they brought out pieces of bread. He said: "Is there no condiment?" They said: "No, except for some vinegar." He said: "Bring it near, for vinegar is an excellent condiment." Jabir said: "I have not ceased to love vinegar since I heard it from the Messenger of Allah (peace and blessings of Allah be upon him)." And Talha said: "I have not ceased to love vinegar since I heard it from Jabir."
