عَنْ عَمْرَةَ عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّهَا قَالَتْ كُنَّا نَنْبِذُ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ غُدْوَةً فِي سِقَاءٍ وَلَا نُخَمِّرُهُ وَلَا نَجْعَلُ لَهُ عَكَرًا فَإِذَا أَمْسَى تَعَشَّى فَشَرِبَ عَلَى عَشَائِهِ فَإِنْ بَقِيَ شَيْءٌ فَرَّغْتُهُ أَوْ صَبَبْتُهُ ثُمَّ نَغْسِلُ السِّقَاءَ فَنَنْبِذُ فِيهِ مِنَ الْعِشَاءِ فَإِذَا أَصْبَحَ تَغَدَّى فَشَرِبَ عَلَى غَدَائِهِ فَإِنْ فَضَلَ شَيْءٌ صَبَبْتُهُ أَوْ فَرَّغْتُهُ ثُمَّ غَسَلَ السِّقَاءَ فَقِيلَ لَهَا أَفِيهِ غَسَلَ السِّقَاءَ مَرَّتَيْنِ قَالَتْ مَرَّتَيْنِ
Lady Aisha (may Allah be pleased with her) narrates: We used to prepare nabidh (a drink made from dates or raisins soaked in water) in a waterskin for the Noble Prophet (peace and blessings be upon him) in the morning. We would not cover it, nor would we leave any sediment in it. When evening came and the Prophet (peace and blessings be upon him) had eaten his evening meal, he would then drink the nabidh. If any nabidh was left over, I would pour it out and wash the waterskin. Then we would prepare nabidh at the time of Isha. When morning came and the Prophet (peace and blessings be upon him) had eaten his morning meal, he would drink the nabidh. If any nabidh was left over, I would pour it out, and then the vessel would be washed. Maqatil was asked: Is there mention of washing the waterskin twice in this hadith? He replied: Yes, there is mention of washing it twice.
