حَدَّثَنَا مُسْلِمٌ ، حَدَّثَنَا هِشَامٌ ، حَدَّثَنَا قَتَادَةُ ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ إِنِّي لأَسْقِي أَبَا طَلْحَةَ وَأَبَا دُجَانَةَ وَسُهَيْلَ ابْنَ الْبَيْضَاءِ خَلِيطَ بُسْرٍ وَتَمْرٍ إِذْ حُرِّمَتِ الْخَمْرُ، فَقَذَفْتُهَا وَأَنَا سَاقِيهِمْ وَأَصْغَرُهُمْ، وَإِنَّا نَعُدُّهَا يَوْمَئِذٍ الْخَمْرَ . وَقَالَ عَمْرُو بْنُ الْحَارِثِ حَدَّثَنَا قَتَادَةُ سَمِعَ أَنَسًا .
While I was serving Abu Talha. Abu Dujana and Abu Suhail bin Al-Baida' with a drink made from a mixture of unripe and ripe dates, alcoholic drinks, were made unlawful, whereupon I threw it away, and I was their butler and the youngest of them, and we used to consider that drink as an alcoholic drink in those days.
