"I heard 'Uthman, may Allah be pleased with him, say: 'Avoid Khamr for it is the mother of all evils. There was a man among those who came before you who was a devoted worshipper. An immoral woman fell in love with him. She sent her slave girl to him, saying: We are calling you to bear witness. So he set out with her slave girl, and every time he entered a door, she locked it behind him, until he reached a beautiful woman who has with her a boy and a vessel of wine. She said: 'By Allah, I did not call you to bear witness, rather I called you to have intercourse with me, or to drink a cup of this wine, or to kill this boy.' He said: 'Pour me a cup of this wine.' So she poured him a cup. He said: 'Give me more.' And soon he had intercourse with her and killed the boy. So avoid Khamr, for by Allah faith and addiction to Khamr cannot coexist but, one of them will soon expel the other."  

سَمِعْتُ عُثْمَانَ ؓ يَقُولُ اجْتَنِبُوا الْخَمْرَ فَإِنَّهَا أُمُّ الْخَبَائِثِ إِنَّهُ كَانَ رَجُلٌ مِمَّنْ خَلاَ قَبْلَكُمْ تَعَبَّدَ فَعَلِقَتْهُ امْرَأَةٌ غَوِيَّةٌ فَأَرْسَلَتْ إِلَيْهِ جَارِيَتَهَا فَقَالَتْ لَهُ إِنَّا نَدْعُوكَ لِلشَّهَادَةِ فَانْطَلَقَ مَعَ جَارِيَتِهَا فَطَفِقَتْ كُلَّمَا دَخَلَ بَابًا أَغْلَقَتْهُ دُونَهُ حَتَّى أَفْضَى إِلَى امْرَأَةٍ وَضِيئَةٍ عِنْدَهَا غُلاَمٌ وَبَاطِيَةُ خَمْرٍ فَقَالَتْ إِنِّي وَاللَّهِ مَا دَعَوْتُكَ لِلشَّهَادَةِ وَلَكِنْ دَعَوْتُكَ لِتَقَعَ عَلَىَّ أَوْ تَشْرَبَ مِنْ هَذِهِ الْخَمْرَةِ كَأْسًا أَوْ تَقْتُلَ هَذَا الْغُلاَمَ قَالَ فَاسْقِينِي مِنْ هَذَا الْخَمْرِ كَأْسًا فَسَقَتْهُ كَأْسًا قَالَ زِيدُونِي فَلَمْ يَرِمْ حَتَّى وَقَعَ عَلَيْهَا وَقَتَلَ النَّفْسَ فَاجْتَنِبُوا الْخَمْرَ فَإِنَّهَا وَاللَّهِ لاَ يَجْتَمِعُ الإِيمَانُ وَإِدْمَانُ الْخَمْرِ إِلاَّ لَيُوشِكُ أَنْ يُخْرِجَ أَحَدُهُمَا صَاحِبَهُ  

"I heard 'Uthman say: 'Avoid Khamr for it is the mother of all evils. There was a man among those who came before you who was a devoted worshipper and used to stay away from people.'" And he mentioned something similar. He said: "Avoid Khamr for, by Allah, it can never coexist with Faith, but soon one of them will expel the other."  

سَمِعْتُ عُثْمَانَ يَقُولُ اجْتَنِبُوا الْخَمْرَ فَإِنَّهَا أُمُّ الْخَبَائِثِ فَإِنَّهُ كَانَ رَجُلٌ مِمَّنْ خَلاَ قَبْلَكُمْ يَتَعَبَّدُ وَيَعْتَزِلُ النَّاسَ فَذَكَرَ مِثْلَهُ قَالَ فَاجْتَنِبُوا الْخَمْرَ فَإِنَّهُ وَاللَّهِ لاَ يَجْتَمِعُ وَالإِيمَانُ أَبَدًا إِلاَّ يُوشِكُ أَحَدُهُمَا أَنْ يُخْرِجَ صَاحِبَهُ  

"Whoever drinks Khamr and does not get intoxicated, his Salah will not be accepted so long as any trace of it remains in his belly or his veins, and if he dies he will die a Kafir. If he becomes intoxicated his Salah will not be accepted for 40 nights, and if he dies during them, he will die a Kafir." (Sahih Mawquf)  

مَنْ شَرِبَ الْخَمْرَ فَلَمْ يَنْتَشِ لَمْ تُقْبَلْ لَهُ صَلاَةٌ مَادَامَ فِي جَوْفِهِ أَوْ عُرُوقِهِ مِنْهَا شَىْءٌ وَإِنْ مَاتَ مَاتَ كَافِرًا وَإِنِ انْتَشَى لَمْ تُقْبَلْ لَهُ صَلاَةٌ أَرْبَعِينَ لَيْلَةً وَإِنْ مَاتَ فِيهَا مَاتَ كَافِرًا خَالَفَهُ يَزِيدُ بْنُ أَبِي زِيَادٍ  

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
