(3) باب نَفَقَةِ نِسَاءِ النَّبِيِّ صلى الله عليه وسلم بَعْدَ وَفَاتِهِ
Narrated Aisha:
Allah's Messenger (ﷺ) died, and there was nothing in my house that a living being could eat, except some barley Lying on a shelf. So, I ate of it for a long period and measured it, and (after a short period) it was consumed.
