The wine on that day is al-Basr: the dates before they are moistened, and the dates

وحدثني بعض أصحابي: أنه سمع أنس بن مالك يقول: كانت خمرهم يومئذ.(5262) - حدثنا محمد بن أبي بكر المُقَدَّمي: حدثنا يوسف أبو معشر البرَّاء قال: سمعت سعيد بن عبيد الله قال: حدثني بكر بن عبد الله: أن أنس بن مالك حدثهم: أن الخمر حُرِّمت، والخمر يومئذ البُسْر والتمر.

Some of my companions told me: He heard Anas bin Malik say: Their wine was on that day. (5262) - Muhammad bin Abi Bakr Al-Muqaddimi told us: Youssef Abu Muasher Al-Bara’ told us, he said: I heard Saeed bin Ubaid Allah say: Bakr bin Abdullah told me: Anas bin Malik told them: that wine was forbidden, and wine on that day was Bisr and dates.

Bisr: dates before they are moistened
