"‏ مَنْ شَرِبَ الْخَمْرَ لَمْ يَقْبَلِ اللَّهُ لَهُ صَلاَةً أَرْبَعِينَ صَبَاحًا فَإِنْ تَابَ تَابَ اللَّهُ عَلَيْهِ فَإِنْ عَادَ لَمْ يَقْبَلِ اللَّهُ لَهُ صَلاَةً أَرْبَعِينَ صَبَاحًا فَإِنْ تَابَ تَابَ اللَّهُ عَلَيْهِ فَإِنْ عَادَ لَمْ يَقْبَلِ اللَّهُ لَهُ صَلاَةً أَرْبَعِينَ صَبَاحًا فَإِنْ تَابَ تَابَ اللَّهُ عَلَيْهِ فَإِنْ عَادَ الرَّابِعَةَ لَمْ يَقْبَلِ اللَّهُ لَهُ صَلاَةً أَرْبَعِينَ صَبَاحًا فَإِنْ تَابَ لَمْ يَتُبِ اللَّهُ عَلَيْهِ وَسَقَاهُ مِنْ نَهْرِ الْخَبَالِ ‏"

That the Messenger of Allah (ﷺ) said: "Whoever drinks Khamr, Salat is not accepted from him for forty days. If he repents, then Allah will accept his repentance. It he returns to it, then Allah will not accept his Salat for forty days. If he repents, then Allah will accept his repentance. If he returns to it, then Allah will not accepts his Salat for forty days. If he repents, then Allah will accept his repentance. If he returns to it a fourth time, Allah will not accept his Salat for forty days, and if he were to repent, Allah would not accept his repentance, and he will be given to drink from the river of Al-Khabal." They said: "O Aby 'Abdur-Rahman! What is the river of Al-Khabal?" He said: "A river of the pus from the inhabitants of the Fire." [Abu 'Eisa said:] This Hadith is Hasan. Similar to this has been reported from 'Abdullah bin 'Amr and Ibn 'Abbas from the Prophet (ﷺ).
