Musnad Ahmad 31:679

Hassan narrated to us, Ibn Lahi'ah narrated to us, Ibn Hubayrah narrated to us, from Hanash ibn Abdullah, that he heard Abu Sa'id al-Khudri saying: The Messenger of Allah (peace and blessings of Allah be upon him) led us in prayer one day, and he perceived the odor of garlic from a man. When he finished, he said to him: "One of you goes and eats of this foul thing, then he comes and harms us."
