Narrated Anas ibn Malik:

I was serving wine to the people in the house of AbuTalhah when it was prohibited and that day our wine was made from unripe dates. A man entered upon us and said: The wine has been prohibited, and the herald of the Messenger of Allah (ﷺ) made an announcement. We then said: This is the herald of the Messenger of Allah (ﷺ)

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، قَالَ كُنْتُ سَاقِيَ الْقَوْمِ حَيْثُ حُرِّمَتِ الْخَمْرُ فِي مَنْزِلِ أَبِي طَلْحَةَ وَمَا شَرَابُنَا يَوْمَئِذٍ إِلاَّ الْفَضِيخُ فَدَخَلَ عَلَيْنَا رَجُلٌ فَقَالَ إِنَّ الْخَمْرَ قَدْ حُرِّمَتْ وَنَادَى مُنَادِي رَسُولِ اللَّهِ صلى الله عليه وسلم فَقُلْنَا هَذَا مُنَادِي رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏
