The Prophet [SAW] said: "Whoever drinks Khamr and puts it in his belly, Allah will not accept his Salah for seven (days), if he dies during them" - Muhammad bin Adam (One of the narrators) said: "he will die a Kafir. If he was too intoxicated to offer any of the obligatory" - Ibn Adam said: "or recite Qur'an, his Salah will not be accepted for 40 days, and if he dies during them," And Ibn Adam said: "He will die a Kafir."  

عَنِ النَّبِيِّ ﷺ وَقَالَ مُحَمَّدُ بْنُ آدَمَ عَنْ رَسُولِ اللَّهِ ﷺ قَالَ مَنْ شَرِبَ الْخَمْرَ فَجَعَلَهَا فِي بَطْنِهِ لَمْ يَقْبَلِ اللَّهُ مِنْهُ صَلاَةً سَبْعًا إِنْ مَاتَ فِيهَا وَقَالَ ابْنُ آدَمَ فِيهِنَّ مَاتَ كَافِرًا فَإِنْ أَذْهَبَتْ عَقْلَهُ عَنْ شَىْءٍ مِنَ الْفَرَائِضِ وَقَالَ ابْنُ آدَمَ الْقُرْآنِ لَمْ تُقْبَلْ لَهُ صَلاَةٌ أَرْبَعِينَ يَوْمًا إِنْ مَاتَ فِيهَا وَقَالَ ابْنُ آدَمَ فِيهِنَّ مَاتَ كَافِرًا  

[Machine] Narrated by the Prophet ﷺ : "Whoever drinks alcohol and lets it enter his stomach, his prayers will not be accepted from him for seven days. And if he dies while in that state, he dies as disbeliever. And if his mind is distracted from fulfilling any of the obligatory duties, his prayers will not be accepted from him for forty days. And if he dies during that time, he dies as disbeliever."  

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ شَرِبَ الْخَمْرَ فَجَعَلَهَا فِي بَطْنِهِ لَمْ تُقْبَلْ مِنْهُ صَلَاةٌ سَبْعًا وَإِنْ مَاتَ فِيهِ مَاتَ كَافِرًا فَإِنْ أَذْهَلَتْ عَقْلَهُ عَنْ شَيْءٍ مِنَ الْفَرَائِضِ لَمْ تُقْبَلْ لَهُ صَلَاةٌ أَرْبَعِينَ يَوْمًا وَإِنْ مَاتَ فِيهَا مَاتَ كَافِرًا»  

"مَنْ شَرِبَ الخَمْرَ فَجَعَلَها في بَطنِهِ لَمْ يَقْبَلِ الله مِنْهُ صَلاةً سَبْعًا، فَإِنْ مَاتَ فِيهن مَاتَ كَافِرًا، فَإِنْ أَذْهَبَ عَقْلَهُ عَنْ شَيْءٍ مِنَ الفَرَائِضِ، لَمْ تُقْبَلْ لَهُ صَلاةٌ أَرْبَعِينَ يَوْمًا، فَإِنْ مَاتَ فِيهن مَاتَ كَافِرًا".
