حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا الْمُعْتَمِرُ، قَالَ سَمِعْتُ شَبِيبَ بْنَ عَبْدِ الْمَلِكِ، يُحَدِّثُ عَنْ مُقَاتِلِ بْنِ حَيَّانَ، قَالَ حَدَّثَتْنِي عَمَّتِي، عَمْرَةُ عَنْ عَائِشَةَ، رضى الله عنها أَنَّهَا كَانَتْتَنْبِذُ لِلنَّبِيِّ صلى الله عليه وسلم غُدْوَةً فَإِذَا كَانَ مِنَ الْعَشِيِّ فَتَعَشَّى شَرِبَ عَلَى عَشَائِهِ وَإِنْ فَضَلَ شَىْءٌ صَبَبْتُهُ - أَوْ فَرَغْتُهُ - ثُمَّ تَنْبِذُ لَهُ بِاللَّيْلِ فَإِذَا أَصْبَحَ تَغَدَّى فَشَرِبَ عَلَى غَدَائِهِ قَالَتْ نَغْسِلُ السِّقَاءَ غُدْوَةً وَعَشِيَّةً فَقَالَ لَهَا أَبِي مَرَّتَيْنِ فِي يَوْمٍ قَالَتْ نَعَمْ ‏.‏
Translation
Narrated Aisha, Ummul Mu'minin

Aisha (may Allah be pleased with her) used to steep dates for the Prophet (ﷺ) in the morning, and when evening came, he would have his dinner and drink from it. If anything was left over, she would pour it out (or empty it). Then she would steep for him at night, and when morning came, he would have his breakfast and drink from it. She said: We used to wash the water-skin in the morning and in the evening. My father said to her twice a day? She said: Yes.
