Ibn Ad-Dailami rode looking for 'Abdullah bin 'Amr bin Al-'As. Ibn Ad-Dailami said: "I entered upon him and said: 'O 'Abdullah bin 'Amr, did you hear the Messenger of Allah [SAW] say anything concerning Khamr?' He said: 'Yes, I heard the Messenger of Allah [SAW] say: If a man among my Ummah drinks Khamr, Allah will not accept his Salah for forty days.'"  

سَمِعْتَ يَا عَبْدَ اللَّهِ بْنَ عَمْرٍو رَسُولَ اللَّهِ ﷺ ذَكَرَ شَأْنَ الْخَمْرِ بِشَىْءٍ فَقَالَ نَعَمْ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ يَشْرَبُ الْخَمْرَ رَجُلٌ مِنْ أُمَّتِي فَيَقْبَلُ اللَّهُ مِنْهُ صَلاَةً أَرْبَعِينَ يَوْمًا  

"If a judge accepts a gift he has consumed something unlawful, and if he accepts a bribe, that takes him to the level of Kufr." Masruq said: "Whoever drinks Khamr, he has committed (an act of) Kufr, and his Kufr is that his Salah does not count."  

الْقَاضِي إِذَا أَكَلَ الْهَدِيَّةَ فَقَدْ أَكَلَ السُّحْتَ وَإِذَا قَبِلَ الرِّشْوَةَ بَلَغَتْ بِهِ الْكُفْرَ وَقَالَ مَسْرُوقٌ مَنْ شَرِبَ الْخَمْرَ فَقَدْ كَفَرَ وَكُفْرُهُ أَنْ لَيْسَ لَهُ صَلاَةٌ
