Sahih Muslim Book - 36, Hadith - 5215

حَدَّثَنَا مُحَمَّدُ بْنُ عَبَّادٍ ، حَدَّثَنَا سُفْيَانُ ، عَنْ عَمْرٍو ، سَمِعَهُ مِنْ سَعِيدِ بْنِ أَبِي بُرْدَةَ ، عَنْ أَبِيهِ ، عَنْ جَدِّهِ ، أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَعَثَهُ وَمُعَاذًا إِلَى الْيَمَنِ ، فَقَالَ لَهُمَا : بَشِّرَا وَيَسِّرَا ، وَعَلِّمَا وَلاَ تُنَفِّرَا ، وَأُرَاهُ قَالَ: وَتَطَاوَعَا ، قَالَ: فَلَمَّا وَلَّى رَجَعَ أَبُو مُوسَى ، فَقَالَ: يَا رَسُولَ اللهِ ، إِنَّ لَهُمْ شَرَابًا مِنَ الْعَسَلِ يُطْبَخُ حَتَّى يَعْقِدَ ، وَالْمِزْرُ يُصْنَعُ مِنَ الشَّعِيرِ ، فَقَالَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: كُلُّ مَا أَسْكَرَ عَنِ الصَّلاَةِ فَهُوَ حَرَامٌ.

It was narrated from Sa'eed bin Abi Burdah, from his father, from his grandfather, that the Prophet (s.a.w) sent him and Mu'adh to Yemen and he said to them: "Give glad tidings and make things easy, teach and do not repulse people." And I think he said: "And cooperate." When he turned to leave, Abu Musa came back and said: "O Messenger of Allah, they have a drink made of honey which is cooked until it becomes thick, and Al-Mizr, which is made of barley." The Messenger of Allah (s.a.w) said: "Everything that detains (a person) from As-Salat (prayer) is Haram.''
