Sahih al-Bukhari, Volume 8, Book 76, Hadith 466 (USC-MSA) ⓘ
Narrated `Aisha: that she said to `Urwa, "O, the son of my sister! We used to see three crescents in two months, and no fire used to be made in the houses of Allah's Messenger (i.e. nothing used to be cooked)." `Urwa said, "What used to sustain you?" `Aisha said, "The two black things i.e. dates and water, except that Allah's Messenger had neighbors from the Ansar who had some milch she-camels, and they used to give the Prophet some milk from their house, and he used to make us drink it."
حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ الأُوَيْسِيُّ، حَدَّثَنِي ابْنُ أَبِي حَازِمٍ، عَنْ أَبِيهِ، عَنْ يَزِيدَ بْنِ رُومَانَ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، أَنَّهَا قَالَتْ لِعُرْوَةَ ابْنَ أُخْتِي إِنْ كُنَّا لَنَنْظُرُ إِلَى الْهِلاَلِ ثَلاَثَةَ أَهِلَّةٍ فِي شَهْرَيْنِ، وَمَا أُوقِدَتْ فِي أَبْيَاتِ رَسُولِ اللَّهِ صلى الله عليه وسلم نَارٌ. فَقُلْتُ مَا كَانَ يُعِيشُكُمْ قَالَتِ الأَسْوَدَانِ التَّمْرُ وَالْمَاءُ إِلاَّ أَنَّهُ قَدْ كَانَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم جِيرَانٌ مِنَ الأَنْصَارِ كَانَ لَهُمْ مَنَائِحُ، وَكَانُوا يَمْنَحُونَ رَسُولَ اللَّهِ صلى الله عليه وسلم مِنْ أَبْيَاتِهِمْ، فَيَسْقِينَاهُ.
