Sahih Bukhari Volume 8, Book 81, Hadith 6460

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى، حَدَّثَنَا هِشَامٌ، أَخْبَرَنِي أَبِي، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كَانَ يَأْتِي عَلَيْنَا الشَّهْرُ مَا نُوقِدُ فِيهِ نَارًا، إِنَّمَا هُوَ التَّمْرُ وَالْمَاءُ، إِلاَّ أَنْ نُؤْتَى بِاللُّحَيْمِ‏.‏

Narrated By 'Aisha : A complete month would pass by during which we would not make a fire (for cooking), and our food used to be only dates and water unless we were given a present of some meat.
