Musnad Ahmad 30:1694

Haytham narrated to us, he said: Hafs ibn Maysarah informed us, from al-Ala’ ibn Abd al-Rahman, from his father, from Abu Hurayrah, that the Prophet, peace and blessings of Allah be upon him, said: "Every human being that his mother gives birth to, the Shaytan pokes him in his two sides, except for what was of Maryam and her son. Have you not seen the infant when he falls, how he screams?" They said: "Yes, O Messenger of Allah." He said: "That is when the Shaytan pokes him in his two sides."
