Hadith 14:82
‘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.
وَعَنْ عَائِشَةَ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَا أسكرَ مِنْهُ الفرْقُ فَمِلْءُ الْكَفِّ مِنْهُ حَرَامٌ» . رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَأَبُو دَاوُد
