حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ، أَخْبَرَنَا عِيسَى، وَابْنُ، إِدْرِيسَ عَنْ أَبِي حَيَّانَ، عَنِ الشَّعْبِيِّ، عَنِ ابْنِ عُمَرَ، قَالَ سَمِعْتُ عُمَرَ ـ رضى الله عنه ـ عَلَى مِنْبَرِ النَّبِيِّ صلى الله عليه وسلم يَقُولُ أَمَّا بَعْدُ أَيُّهَا النَّاسُ إِنَّهُ نَزَلَ تَحْرِيمُ الْخَمْرِ وَهْىَ مِنْ خَمْسَةٍ، مِنَ الْعِنَبِ وَالتَّمْرِ وَالْعَسَلِ وَالْحِنْطَةِ وَالشَّعِيرِ، وَالْخَمْرُ مَا خَامَرَ الْعَقْلَ‏.‏

Narrated Ibn `Umar: I heard `Umar while he was on the pulpit of the Prophet (PBUH) saying, "Now then O people! The revelation about the prohibition of alcoholic drinks was revealed; and alcoholic drinks are extracted from five things: Grapes, dates, honey, wheat and barley. And the alcoholic drink is that which confuses and stupefies the mind." Translation Not Available
