sahih

Narrated Jabir:

Some people drank alcoholic beverages in the morning (of the day) of the Uhud battle and on the same day they were killed as martyrs, and that was before wine was prohibited.

حَدَّثَنَا صَدَقَةُ بْنُ الْفَضْلِ، أَخْبَرَنَا ابْنُ عُيَيْنَةَ، عَنْ عَمْرٍو، عَنْ جَابِرٍ، قَالَ صَبَّحَ أُنَاسٌ غَدَاةَ أُحُدٍ الْخَمْرَ فَقُتِلُوا مِنْ يَوْمِهِمْ جَمِيعًا شُهَدَاءَ، وَذَلِكَ قَبْلَ تَحْرِيمِهَا‏.‏
