´It was narrated that Hisham bin 'A'idh Al-Asadi said:` "I asked Ibrahim about juice and he said: 'Drink it, unless it bubbles, so long as it doesn't change.'"
Explanation & Benefits
Hafiz Muhammad Ameen
This ruling is not specific to grape juice alone, but applies to the juice of any fruit. Or if preservatives are added to it, for example: squash, which becomes bitter like vinegar but, due to a specific medicine, no fermentation or change occurs in it and it does not become intoxicating. Therefore, squash made from any fruit may be used.
