Must we be certain that every child's cry at birth is due to the prick of Satan as mentioned by the Prophet (peace be upon him), or does the hadith refer to the majority of people, and is doubting this considered disbelief?

The Hadith indicates that Satan stabs every newborn of Adam's descendants at birth, causing them to cry out, except for Mary and her son Jesus, peace be upon them. Allah protected them by the blessing of Mary's mother's prayer: "And I seek refuge for her in You and for her descendants from Satan, the expelled [from Your mercy]." One must believe in this as it was narrated from the Prophet, peace and blessings be upon him, and no one is exempted other than those mentioned in the Hadith.
