Abu Huraira said, “I heard Allah’s Messenger (ﷺ) saying, ‘There is none born among the off-spring of Adam, but Satan touches it. A child therefore, cries loudly at the time of birth because of the touch of Satan, except Mary and her child.” Then Abu Huraira recited: “And I seek refuge with You for her and for her offspring from the outcast Satan” (3.36) Sahih al-Bukhari Book 60, Hadith 102.
