Tirmidhi

Explanation:
1:
Because when mixed (when both are combined), intoxication develops in it rapidly,
even though its color does not change,
therefore, the one who drinks it assumes that it is not yet intoxicating.

Benefits and Issues:
Benefit: According to the explanation mentioned in Nihayah Ibn Athir, one of the methods of making intoxicating nabidh in the pre-Islamic era was that raisins and dates, or ripe fresh dates and semi-ripe dates, were mixed with water and then boiled.
Then it would be left for such a duration that intensity (fermentation) would develop in it.
It is narrated from Layth ibn Sa'd that when two different things were mixed, intensity would develop very quickly.
And the drink would become intoxicating.
Therefore, nabidh prepared in this manner was prohibited.
In hadith number 3706, this very process has also been explicitly described.
This too has been prohibited; however, if the pulp of fruits is mixed in such a way that the process of fermentation does not occur, then there is no harm in it.
As is made clear from hadith numbers 3707 and 3708.

Benefits and Issues:
➊ If dates, dried dates (chuhaara), or raisins (munqqa) are placed in water, then overnight their sweetness dissolves into the water and a sweet drink is prepared. This is called nabidh. This is a lawful (halal) drink because it does not contain intoxication.

➋ By mixing two types of things to make nabidh, there is a risk that intoxication will develop quickly in it. Therefore, one should avoid this.

➌ If there is a risk that a lawful act may result in the commission of an unlawful act, then it is better to avoid even that lawful act.

➍ In winter, soaking for a longer period also carries less risk of intoxication developing. Whereas in the summer season, its state changes quickly. This can be judged by its taste. If the drink is sweet, it should be drunk. And if the taste changes and bitterness or sourness is felt, then it should be discarded.
