The following relates the story of the millstone and
(may Allah be pleased with her). It is related on the authority of
(may Allah be pleased with him) that the Messenger of Allah (peace be upon him) went to his daughter
(may Allah be pleased with her) and found her grinding barley while weeping, whereupon he said to her: What makes you cry,
She said: Because of the household chores and the grinding. If you ask
(may Allah be pleased with him) to hire a servant, he will be greatly rewarded. When the Prophet (peace be upon him) heard that, his heart softened for her and his eyes moved to tears. He, accordingly, sat beside the millstone, took a handful of barley with his blessed hand, and said: Bismillah Al-Rahman, Al-Rahim [In the Name of Allah, the Most Gracious, the Most Merciful], and started throwing barley in the millstone. When it started turning on, the Prophet (peace be upon him) heard it glorifying Allah (Glorified and Exalted be He) with eloquent words and a beautiful sound, and he continued like that until the barley ran out. The Prophet (peace be upon him) ordered the millstone to stop grinding, but Allah (Exalted be He) Who causes all things to speak made it speak to say to the Prophet (peace be upon him): By Him Who has sent you with the truth, I would not stop grinding until you supplicate to Allah that I be admitted into Jannah (Paradise) and saved from the Fire.
