The Meaning of Combining Two Mixtures and the Ruling on Mixed Beverages

Question:
He says: It is reported in the hadith: "Do not brew more than three, and do not combine two mixtures." What is meant by combining two mixtures? And what is the ruling on what is called mixed juice or cocktail?

Answer:
The two mixtures are combining dates with grapes, meaning two substances. A wine made from two substances, dates and grapes, or raisins and grapes, is made from two substances. This is the "two mixtures." There is a problem with this; because if it is made from two substances, it becomes strong enough to ferment, unlike when it is made from one substance, in which case it does not become strong enough to ferment unless three days have passed. This is the "two mixtures." As for the mixed bottled drinks now, as we mentioned, these are preserved now and contain substances that prevent their fermentation, so there is no harm even if they are mixed. Peace be upon you. It is not like the two mixtures that were prohibited. Yes.
