Narrated Anas bin Malik:

I was serving Abu 'Ubaida, Abu Talha and Ubai bin Ka'b with a drink prepared from ripe and unripe dates. Then somebody came to them and said, "Alcoholic drinks have been prohibited." (On hearing that) Abu Talha said, "Get up. O Anas, and pour (throw) it out! So I poured (threw) it out.

حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنِي مَالِكُ بْنُ أَنَسٍ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ كُنْتُ أَسْقِي أَبَا عُبَيْدَةَ وَأَبَا طَلْحَةَ وَأُبَىَّ بْنَ كَعْبٍ مِنْ فَضِيخِ زَهْوٍ وَتَمْرٍ فَجَاءَهُمْ آتٍ فَقَالَ إِنَّ الْخَمْرَ قَدْ حُرِّمَتْ. فَقَالَ أَبُو طَلْحَةَ قُمْ يَا أَنَسُ فَأَهْرِقْهَا. فَأَهْرَقْتُهَا.
