Mishkat al-Masabih #3492

‘A’isha reported God’s Messenger as saying, “If a faraq of anything causes intoxication, a handful of it is forbidden.”* Ahmad, Tirmidhi and Abu Dawud transmitted it. * To drink as much as a faraq (see p. 577) would be almost impossible, so the point of the tradition is to forbid anything which might in any conceivable circumstances cause intoxication.
