باب عُقُوبَةِ مَنْ شَرِبَ الْخَمْرَ إِذَا لَمْ يَتُبْ مِنْهَا بِمَنْعِهِ إِيَّاهَا فِي الآخِرَةِ ‏‏
Sahih Muslim 2003 f

Ibn 'Umar said:

He who drank wine in the world and did not repent would be deprived of it (the pure drink) in the Hereafter. It was said to Malik: Is this hadith Marfu'? He said: Yes.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، حَدَّثَنَا مَالِكٌ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ ‏ "‏ مَنْ شَرِبَ الْخَمْرَ فِي الدُّنْيَا فَلَمْ يَتُبْ مِنْهَا حُرِمَهَا فِي الآخِرَةِ فَلَمْ يُسْقَهَا ‏"‏ ‏.‏ قِيلَ لِمَالِكٍ رَفَعَهُ قَالَ نَعَمْ ‏.‏
