It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Once, when I was a child playing with other children, suddenly a man came and he grabbed me and split open my stomach. He took out a clot of congealed blood from it and threw it away, saying, "This was the portion of Satan in your body." Then he washed my stomach with Zamzam water from a golden basin, and then he stitched it up and closed it. Seeing this, all the children ran to my mother and said, "Muhammad (peace and blessings be upon him) has been killed." My mother came running and saw that the color of the blessed face of the Prophet (peace and blessings be upon him) was changing. Hazrat Anas (may Allah be pleased with him) says that we used to see the marks of the stitching on the blessed chest of the Prophet (peace and blessings be upon him).
