This hadith is about the prohibition of intoxicants. The Messenger of Allah said that every intoxicant is unlawful and whatever causes intoxication in large amounts, a small amount of it is also unlawful. This means that any substance which can cause intoxication or drunkenness, even if it's only a small amount, is prohibited and not allowed to be consumed.
