Musnad Abu Ya'la al-Mawsili 117:233

Zuhayr narrated to us, Affan narrated to us, Hammad narrated to us, Thabit informed us, from Anas, that Gabriel came to the Messenger of Allah (ﷺ) while he was playing with the boys. He took him, threw him down, and split open his chest. He extracted a blood clot from it and said, "This is the portion of Satan in you." Then he washed it in a golden basin with Zamzam water. Then he joined it together and returned it to its place. The boys came running to his mother—meaning his wet nurse—and said, "Indeed, Muhammad has been killed." They went to meet him, and he was pale in color. Anas said: "And I used to see the mark of the needle on his chest." And perhaps Hammad said: "Indeed, someone came to the Messenger of Allah (ﷺ)."
