Sahih Muslim Book - 36, Hadith - 5226

حَدَّثَنَا عُبَيْدُ اللهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا شُعْبَةُ ، عَنْ يَحْيَى بْنِ عُبَيْدٍ أَبِي عُمَرَ الْبَهْرَانِيِّ ، قَالَ: سَمِعْتُ ابْنَ عَبَّاسٍ ، يَقُولُ: كَانَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُنْتَبَذُ لَهُ أَوَّلَ اللَّيْلِ ، فَيَشْرَبُهُ إِذَا أَصْبَحَ يَوْمَهُ ذَلِكَ ، وَاللَّيْلَةَ الَّتِي تَجِيءُ ، وَالْغَدَ وَاللَّيْلَةَ الأُخْرَى ، وَالْغَدَ إِلَى الْعَصْرِ ، فَإِنْ بَقِيَ شَيْءٌ سَقَاهُ الْخَادِمَ ، أَوْ أَمَرَ بِهِ فَصُبَّ.

Ibn 'Abbas said: "Nabidh would be made for the Messenger of Allah (s.a.w) at the beginning of the night, and he would drink it the next morning, during that day and the night, then during the following day and night, and the next day until 'Asr. Then if there was anything left of it, he would give it to his servant to drink or order that it be poured away."
