حَدَّثَنَا يَحْيَى بْنُ يَحْيَى حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِى حَازِمٍ عَنْ أَبِيهِ عَنْ يَزِيدَ بْنِ رُومَانَ عَنْ عُرْوَةَ عَنْ عَائِشَةَ أَنَّهَا كَانَتْ تَقُولُ وَاللَّهِ يَا ابْنَ أُخْتِى إِنْ كُنَّا لَنَنْظُرُ إِلَى الْهِلاَلِ ثُمَّ الْهِلاَلِ ثُمَّ الْهِلاَلِ ثَلاَثَةَ أَهِلَّةٍ فِى شَهْرَيْنِ وَمَا أُوقِدَ فِى أَبْيَاتِ رَسُولِ اللَّهِ -صلى الله عليه وسلم- نَارٌ - قَالَ - قُلْتُ يَا خَالَةُ فَمَا كَانَ يُعَيِّشُكُمْ قَالَتِ الأَسْوَدَانِ التَّمْرُ وَالْمَاءُ إِلاَّ أَنَّهُ قَدْ كَانَ لِرَسُولِ اللَّهِ -صلى الله عليه وسلم- جِيرَانٌ مِنَ الأَنْصَارِ وَكَانَتْ لَهُمْ مَنَائِحُ فَكَانُوا يُرْسِلُونَ إِلَى رَسُولِ اللَّهِ -صلى الله عليه وسلم- مِنْ أَلْبَانِهَا فَيَسْقِينَاهُ.

It was narrated from 'Urwah that 'Aishah used to say: "By Allah, O son of my sister, we used to look at the crescent moon, then the crescent moon, then the crescent moon, three crescent moons in two months. And no fire would be lit in the houses of the Messenger of Allah (s.a.w)." I said: "O aunt, what did you live on?" She said: "The two black ones, dates and water, but the Messenger of Allah (s.a.w) had some neighbors from among the Ansar, and they had milch-animals, and they would send some of their milk to the Messenger of Allah (s.a.w), and he would give it to us to drink."
