The Book of Drinks
What Kind of Thickened Grape Juice is Permissible to Drink and What Kind is Not Permitte
أَخْبَرَنَا سُوَيْدٌ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ بَشِيرِ بْنِ الْمُهَاجِرِ، قَالَ سَأَلْتُ الْحَسَنَ عَمَّا يُطْبَخُ مِنَ الْعَصِيرِ قَالَ مَا تَطْبُخُهُ حَتَّى يَذْهَبَ الثُّلُثَانِ وَيَبْقَى الثُّلُثُ .
It was narrated that Bushair bin Al-Muhajir said: "I asked Al-Hasan about juice that has been cooked. He said: 'That which has been cooked until two-third of it has gone and one-third is left.'"
