Mishkat al-Masabih 4287
‘A’isha said:
We used to steep dates for God’s messenger in a skin which was tied at the top and had a mouth. What we steeped in the morning he would drink in the evening, and what we steeped in the evening he would drink in the morning. 

Muslim transmitted it.
وَعَن عائشةَ قَالَتْ: كُنَّا نَنْبِذُ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي سِقَاءٍ يُوكَأُ أَعْلَاهُ وَلَهُ عَزْلَاءُ نَنْبِذُهُ غُدْوَةً فَيَشْرَبُهُ عِشَاءً وَنَنْبِذُهُ عِشَاءً فيشربُه غُدوةً. رَوَاهُ مُسلم
