أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ دَاوُدَ، قَالَ سَأَلْتُ سَعِيدًا مَا الشَّرَابُ الَّذِي أَحَلَّهُ عُمَرُ رضى الله عنه قَالَ الَّذِي يُطْبَخُ حَتَّى يَذْهَبَ ثُلُثَاهُ وَيَبْقَى ثُلُثُهُ ‏.‏

It was narrated that Dawud said: "I asked Sa'eed: 'What is the drink that 'Umar bin Al-Khattab, may Allah be pleased with him, regarded as permissible?' He said: 'That which has been cooked until two-third has gone and one-third is left.'" Translation Not Available
