Bukhari

Hadith Commentary:
The issue regarding the grandfather is whether the grandfather will exclude the brother (from inheritance), or will he himself be excluded by the brother, or will there be sharing (muqasamah) between them.

The issue of usury (riba) is whether, apart from those six items mentioned in the hadith, it is also forbidden to exchange other items in unequal amounts or not. Regarding this, Hafiz (rahimahullah) states: "This (issue) did not exist during the time of the Prophet sallallahu alayhi wa sallam, and if there had been a prohibition regarding it, except that (the Prophet) has generalized the ruling to all intoxicating drinks, saying: 'Khamr is that which clouds the mind.'" (Fath)

That is, if this wine had been distilled from rice, the Prophet sallallahu alayhi wa sallam would have clearly stated its ruling as well, because he has given a general ruling regarding all intoxicating drinks, saying that every drink which removes the intellect is khamr (wine), and it is forbidden.

Hadith Commentary:
(1)
The noble hadith scholars state that anything which covers (veils) the intellect is khamr (intoxicant), and it is forbidden (haram).
If a drink of this type, when consumed in large quantity, causes intoxication, then even a small amount of it is prohibited, even if it is just a single sip.
The basis of this position is the sermon of Sayyiduna Umar radi Allahu anhu, which he delivered before all the noble Companions radi Allahu anhum while standing upon the pulpit of the Messenger of Allah sallallahu alayhi wa sallam.
Rationally, the cause (‘illah) for its prohibition is the potential for intoxication present in the drink, not its actual intoxicating effect.
(2)
The position of the people of Kufa is that the original (real) khamr is that which is prepared from grapes; drinking it in any amount, whether little or much, is forbidden.
If wine is prepared from things other than grapes, it may be called khamr metaphorically, but in reality, it cannot be named khamr.
Such a drink will only be forbidden when it is actually intoxicating in practice.
It is permissible and lawful to drink such an amount from which intoxication does not occur, even if it has the potential to intoxicate.
Due to its opposition to numerous ahadith, this position is rejected.
Imam Bukhari rahimahullah has established several chapters in refutation of this position, stating that the cause (‘illah) of prohibition is the potential for intoxication.
Since the Messenger of Allah sallallahu alayhi wa sallam has stated a general principle regarding all forbidden drinks: every drink that removes the intellect is khamr.
The same ruling applies to a drink prepared from rice; if its use causes intoxication, it is forbidden.
If it is devoid of the potential for intoxication, then it is not forbidden.
And Allah is the One whose help is sought.

Benefits and Issues:
Benefit: The statement of some people that only that is considered wine (khamr) which is made from grapes is not correct. Rather, every substance that is prepared from any kind of material and that veils the intellect is khamr, and it is forbidden, regardless of what it is made from.
