If you desire, I will tell you about Isa (AS) son of Maryam (Mary). He used a stone for his pillow, put on coarse clothes and ate rough food. His condiment was hunger. His lamp at night was the moon. His shade during the winter was just the expanse of earth eastward and westward. His fruits and flowers were only what grows out of the earth for the cattle. He had no wife to allure him, nor any son to grieve him, nor wealth to deviate (his attention), nor greed to disgrace him. His two feet were his conveyance and his two hands his servant.
