Brigham Young's daughter's prayer for forgiveness

While the family was in Kirtland, Brigham Young's daughter broke a saucer. Her mother promised to whip her upon returning from a visit. The child went under an apple tree and prayed that her mother's heart would be softened and she would not whip her. When the mother returned, she had no disposition to chastise the child. Joseph Smith was moved to tears upon hearing this story.

Fuller account of this event (in the witness’s own words):

I referred to an original circumstance which took place in my family. My daughter had broke a saucer; her mother promised her a whipping, when she returned from a visit on which she was just starting; she went out under an apple tree and prayed that her mother’s heart might be softened, and when she returned she might not whip her; although her mother was very punctual when she made a promise to her children to fulfil it, yet when she returned she had no disposition to chastise her child. Afterwards the child told her mother that she had prayed to God that she might not whip her. Joseph wept like a child on hearing this simple narrative and its application.
