"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." (Using translation from Nasāʾī 5665)
الْقَاضِي إِذَا أَكَلَ الْهَدِيَّةَ فَقَدْ أَكَلَ السُّحْتَ وَإِذَا قَبِلَ الرِّشْوَةَ بَلَغَتْ بِهِ الْكُفْرَ وَقَالَ مَسْرُوقٌ «مَنْ شَرِبَ الْخَمْرَ فَقَدْ كَفَرَ وَكُفْرُهُ أَنْ لَيْسَ لَهُ صَلَاةٌ»
