It was narrated from Ibn 'Umar that: The Messenger of Allah [SAW] said: "Whoever drinks Khamr in this world and does not repent from that, will be denied it in the Hereafter."
أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، وَالْحَارِثُ بْنُ مِسْكِينٍ، قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، - وَاللَّفْظُ لَهُ - عَنِ ابْنِ الْقَاسِمِ، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ شَرِبَ الْخَمْرَ فِي الدُّنْيَا ثُمَّ لَمْ يَتُبْ مِنْهَا حُرِمَهَا فِي الآخِرَةِ " .
