The Messenger of Allah (may Allah's peace and blessings be upon him) died when my house was void of any edible thing except for a small quantity of barley I had on a shelf and from which I kept eating it for a long time. Then when I measured what was left of it, it soon finished

‘Ā’ishah (may Allah be pleased with her) informs in this Hadīth that the Prophet (may Allah's peace and blessings be upon him) died when her house was void of any edible thing except for a small quantity of barley she had on a shelf and from which she kept eating for a long time. Then when she measured what was left of it, it soon finished, which points to the Prophet's continued blessing in that small amount of food so long as it was not measured, a sign of reliance on Allah. Weighing things in buying and selling is required for the rights of people involved. But it is not recommended to measure your things as you spend or use them.
