Hyrum Smith's Vision of Mother Smith Praying

Upon returning from the Zion's Camp expedition, Hyrum Smith related to his mother, Lucy Mack Smith, that during the difficult journey—specifically during the time of the cholera outbreak—he had a vision or spiritual impression of his mother praying for him and the other members of the camp. This spiritual manifestation provided him comfort and assurance during the trials of the march.

Fuller account of this event (as retold in Lucy Mack Smith, History of Joseph Smith by His Mother, Chapter 42):

When they arrived, they told me of the situation of the camp, and the difficulties which they had encountered. Hyrum said, 'Mother, I have been in many straits, but in the midst of all my afflictions, I have always been able to maintain my faith, and I have never once doubted that I should return to you. I have had a great many trials, but I have had a great many comforts, too. I have seen an open vision, in which I saw you on your knees, under an apple tree, praying for us. And I am sure that it was your prayers that saved our lives, for I felt the influence of your prayers, and I knew that you were praying for us, and that God would hear your prayers, and that we should be preserved.'
