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 كَانَتْ تَنْبِذُ 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 ‏.‏

Narrated Aisha, Ummul Mu'minin: Amrah said on the authority of Aisha that she would steep dates for the Messenger of Allah (PBUH) in the morning. When the evening came, he took his dinner and drank it after his dinner. If anything remained, she poured it out. She then would steep for him at night. When the morning came, he took his morning meal and drank it after his morning meal. She said: The skin vessel was washed in the morning and in the evening. My father (Hayyan) said to her: Twice a day? She said: Yes. Translation Not Available
