Khamr is a Drink (Made) of Unripe Dates and Dried Dates
أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ شُعْبَةَ، عَنْ مُحَارِبِ بْنِ دِثَارٍ، عَنْ جَابِرٍ، - يَعْنِي ابْنَ عَبْدِ اللَّهِ - قَالَ الْبُسْرُ وَالتَّمْرُ خَمْرٌ.
It was narrated that Jabir - meaning bin 'Abdullah - said: "Unripe dates and dried dates are Khamr."
