Is it forbidden for a drinker of intoxicants to enter Paradise if he dies without repentance?

Question:
I have come across in the book al-Targhib wa al-Tarhib by al-Mundhiri the statement of al-Khattabi and al-Baghawi regarding the drinker of intoxicants if he dies without repentance, in the hadith because the drink of the people of Paradise is khamr (intoxicants), and whoever enters Paradise is not forbidden its drink.

Answer:
The principle held by the people of the Sunnah and the community is that the drinker of intoxicants, as well as the one who commits other sins such as [unclear] and religion, the one who severs family ties, the one who consumes riba (usury or interest), the one who swears falsely, and other such sins, that they are subject to Allah’s mercy in this regard, and that they are threatened with entering the Fire. However, if they enter it, they will not remain in it forever. We are all disbelievers [in the sense of having shortcomings], rather, they have a limit to which they will reach. And whoever is threatened with disbelief in this world will not be a disbeliever in the Hereafter, and whoever is not mocked in this world will not be a disbeliever in the Hereafter. This is from the warnings. Allah the Exalted may forgive what He has threatened His servants with. And if they enter Paradise, He will clothe them in iron and give them to drink from its edge, from afar.
Yes, He the Exalted and Glorious may forgive him, just as He forgives them if He wills, and He will admit them into Paradise because of their tawhid (the oneness of Allah), their sincerity, their faith, and their belief. He will admit them into Paradise immediately by His forgiveness. Or He may punish them because they died upon sins, so they will be punished in the Fire according to the measure of their sins, and they have a limit to which they will reach. Then, after the limit ends, they will be taken out of the Fire into Paradise because of the tawhid and [unclear] upon which they died.
So the warnings found in the hadiths and verses, even if they occur, do not mean that their execution is obligatory. It may be executed, or Allah the Exalted and Glorious may forgive it, for He the Exalted and Glorious may execute it or forgive His warning, Mighty and Majestic. And if He promised and you promised, then they broke My promise and My gathering, so breaking the promise and forgiving it is from the sources of [unclear], and it was from the sources of [unclear] by the right of the neighbors, and from the favor of Allah the Exalted and Glorious if He forgives and overlooks, Paradise and High. As for the promise of Paradise and honor, He the Exalted does not break it, rather He fulfills it from what He promised them of Paradise and honor. But He may forgive the warning, erase the sin, and cover the sinner because of his tawhid and sincerity, because of good deeds he performed, by repenting to Allah from that, and so on. Yes.
