What does the Quran say about alcohol?

۞ يَسْـَٔلُونَكَ عَنِ ٱلْخَمْرِ وَٱلْمَيْسِرِ ۖ قُلْ فِيهِمَآ إِثْمٌۭ كَبِيرٌۭ وَمَنَٰفِعُ لِلنَّاسِ وَإِثْمُهُمَآ أَكْبَرُ مِن نَّفْعِهِمَا ۗ وَيَسْـَٔلُونَكَ مَاذَا يُنفِقُونَ قُلِ ٱلْعَفْوَ ۗ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمُ ٱلْءَايَٰتِ لَعَلَّكُمْ تَتَفَكَّرُونَ

They ask you about wine and gambling. Say, "In them is great sin and [yet, some] benefit for people. But their sin is greater than their benefit." And they ask you what they should spend. Say, "The excess [beyond needs]." Thus Allah makes clear to you the verses [of revelation] that you might give thought.

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَقْرَبُوا۟ ٱلصَّلَوٰةَ وَأَنتُمْ سُكَٰرَىٰ حَتَّىٰ تَعْلَمُوا۟ مَا تَقُولُونَ وَلَا جُنُبًا إِلَّا عَابِرِى سَبِيلٍ حَتَّىٰ تَغْتَسِلُوا۟ ۚ وَإِن كُنتُم مَّرْضَىٰٓ أَوْ عَلَىٰ سَفَرٍ أَوْ جَآءَ أَحَدٌۭ مِّنكُم مِّنَ ٱلْغَآئِطِ أَوْ لَٰمَسْتُمُ ٱلنِّسَآءَ فَلَمْ تَجِدُوا۟ مَآءًۭ فَتَيَمَّمُوا۟ صَعِيدًۭا طَيِّبًۭا فَٱمْسَحُوا۟ بِوُجُوهِكُمْ وَأَيْدِيكُمْ ۗ إِنَّ ٱللَّهَ كَانَ عَفُوًّا غَفُورًا

O you who have believed, do not approach prayer while you are intoxicated until you know what you are saying or in a state of janabah, except those passing through [a place of prayer], until you have washed [your whole body]. And if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women and find no water, then seek clean earth and wipe over your faces and your hands [with it]. Indeed, Allah is ever Pardoning and Forgiving.

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِنَّمَا ٱلْخَمْرُ وَٱلْمَيْسِرُ وَٱلْأَنصَابُ وَٱلْأَزْلَٰمُ رِجْسٌۭ مِّنْ عَمَلِ ٱلشَّيْطَٰنِ فَٱجْتَنِبُوهُ لَعَلَّكُمْ تُفْلِحُونَ

O you who have believed, indeed, intoxicants, gambling, [sacrificing on] stone alters [to other than Allah], and divining arrows are but defilement from the work of Satan, so avoid it that you may be successful.

إِنَّمَا يُرِيدُ ٱلشَّيْطَٰنُ أَن يُوقِعَ بَيْنَكُمُ ٱلْعَدَٰوَةَ وَٱلْبَغْضَآءَ فِى ٱلْخَمْرِ وَٱلْمَيْسِرِ وَيَصُدَّكُمْ عَن ذِكْرِ ٱللَّهِ وَعَنِ ٱلصَّلَوٰةِ ۖ فَهَلْ أَنتُم مُّنتَهُونَ

Satan only wants to cause between you animosity and hatred through intoxicants and gambling and to avert you from the remembrance of Allah and from prayer. So will you not desist?

لَيْسَ عَلَى ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ جُنَاحٌۭ فِيمَا طَعِمُوٓا۟ إِذَا مَا ٱتَّقَوا۟ وَّءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ ثُمَّ ٱتَّقَوا۟ وَّءَامَنُوا۟ ثُمَّ ٱتَّقَوا۟ وَّأَحْسَنُوا۟ ۗ وَٱللَّهُ يُحِبُّ ٱلْمُحْسِنِينَ

There is not upon those who believe and do righteousness [any] blame concerning what they have eaten [in the past] if they [now] fear Allah and believe and do righteous deeds, and then fear Allah and believe, and then fear Allah and do good; and Allah loves the doers of good.

وَدَخَلَ مَعَهُ ٱلسِّجْنَ فَتَيَانِ ۖ قَالَ أَحَدُهُمَآ إِنِّىٓ أَرَىٰنِىٓ أَعْصِرُ خَمْرًۭا ۖ وَقَالَ ٱلْءَاخَرُ إِنِّىٓ أَرَىٰنِىٓ أَحْمِلُ فَوْقَ رَأْسِى خُبْزًۭا تَأْكُلُ ٱلطَّيْرُ مِنْهُ ۖ نَبِّئْنَا بِتَأْوِيلِهِۦٓ ۖ إِنَّا نَرَىٰكَ مِنَ ٱلْمُحْسِنِينَ

And there entered the prison with him two young men. One of them said, "Indeed, I have seen myself [in a dream] pressing wine." The other said, "Indeed, I have seen myself carrying upon my head [some] bread, from which the birds were eating. Inform us of its interpretation; indeed, we see you to be of those who do good."

وَمِن ثَمَرَٰتِ ٱلنَّخِيلِ وَٱلْأَعْنَٰبِ تَتَّخِذُونَ مِنْهُ سَكَرًۭا وَرِزْقًا حَسَنًا ۗ إِنَّ فِى ذَٰلِكَ لَءَايَةًۭ لِّقَوْمٍۢ يَعْقِلُونَ

And from the fruits of the palm trees and grapevines you take intoxicant and good provision. Indeed in that is a sign for a people who reason.

لَا فِيهَا غَوْلٌۭ وَلَا هُمْ عَنْهَا يُنزَفُونَ

No bad effect is there in it, nor from it will they be intoxicated.

لَّا يُصَدَّعُونَ عَنْهَا وَلَا يُنزِفُونَ

No headache will they have therefrom, nor will they be intoxicated -

يُسْقَوْنَ مِن رَّحِيقٍۢ مَّخْتُومٍ

They will be given to drink [pure] wine [which was] sealed.

خِتَٰمُهُۥ مِسْكٌۭ ۚ وَفِى ذَٰلِكَ فَلْيَتَنَافَسِ ٱلْمُتَنَٰفِسُونَ

The last of it is musk. So for this let the competitors compete.
