Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: Jibreel (peace be upon him) came to the Prophet (peace and blessings of Allah be upon him). At that time, the Prophet (peace and blessings of Allah be upon him) was playing with children. (That is, this incident took place during the childhood of the Prophet, peace and blessings of Allah be upon him.) He caught the Prophet (peace and blessings of Allah be upon him), laid him down, split open his chest, took out a clot of blood from it and said: This was the portion of Satan within you. Then he placed the blessed heart of the Prophet (peace and blessings of Allah be upon him) in a basin made of gold and washed it with Zamzam water, then put it back in its place. The children ran to your mother, that is, your wet nurse, and said: Muhammad (peace and blessings of Allah be upon him) has been killed. They came to the Prophet (peace and blessings of Allah be upon him) and saw that his complexion had changed. Sayyiduna Anas (may Allah be pleased with him) narrates: I saw the mark of the stitching on the blessed chest of the Prophet (peace and blessings of Allah be upon him).

(Imam Ibn Hibban, may Allah have mercy on him, states:) The incident of the splitting of the blessed chest of the Prophet (peace and blessings of Allah be upon him) (the first time) happened when he was a child and was playing with children. Then a clot of blood was taken out from inside him. Then, when Allah Almighty intended to take the Prophet (peace and blessings of Allah be upon him) on the Mi’raj, He commanded Jibreel (peace be upon him), and he split open the Prophet’s chest a second time. He took out his heart, washed it again, and then put it back in its place. Thus, this happened twice and on two different occasions. There is no contradiction between these two narrations.
