Sunan Ibn Majah, Book 37, Hadith 4283 (In-Book) ⓘ
It was narrated that ‘Aishah said: “We, the family of Muhammad, would stay for a month during which no fire would be lit (for cooking) and we had only dates and water.”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، وَأَبُو أُسَامَةَ عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ إِنْ كُنَّا آلَ مُحَمَّدٍ ـ صلى الله عليه وسلم ـ لَنَمْكُثُ شَهْرًا مَا نُوقِدُ فِيهِ بِنَارٍ مَا هُوَ إِلاَّ التَّمْرُ وَالْمَاءُ . إِلاَّ أَنَّ ابْنَ نُمَيْرٍ قَالَ نَلْبَثُ شَهْرًا .
