Narrated `Aisha:
حَدَّثَنَا قُتَيْبَةُ ، حَدَّثَنَا جَرِيرٌ ، عَنْ مَنْصُورٍ ، عَنْ إِبْرَاهِيمَ ، عَنِ الأَسْوَدِ ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ مَا شَبِعَ آلُ مُحَمَّدٍ صلى الله عليه وسلم مُنْذُ قَدِمَ الْمَدِينَةَ مِنْ طَعَامِ الْبُرِّ ثَلاَثَ لَيَالٍ تِبَاعًا، حَتَّى قُبِضَ.
The family of Muhammad had not eaten wheat bread to their satisfaction for three consecutive days since his arrival at Medina till he died.
