Hadith 5324
Sayyiduna Abu Huraira (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "If the person who drinks while standing were to know what harm is in it, he would vomit it out." The same narration is also transmitted from Sayyiduna Abu Huraira (may Allah be pleased with him) through another chain of transmission.
