Peace be upon you. May Allah accept your deeds. According to Grand Ayatollah Sayyid Sistani (may Allah protect him), if the beverage in question is similar to 'fuqaa' which causes intoxication, it is not permissible to drink it. However, if it is similar to barley water that does not cause intoxication, it is permissible to consume it. Additionally, Grand Ayatollah Sayyid Khamenei (may Allah protect him) states that if it is 'fuqaa' (beer) or intoxicating, it is not permissible to drink, even if it is alcohol-free. However, if it is made from medicinal barley water, it is permissible to consume it as long as one is not aware of any impurity or prohibition associated with it. The responsibility of determining this lies with the individual.
