Sahih Muslim , Book 46, Hadith 40 (In-Book) ⓘ

Abu Huraira reported Allah's Messenger as saying: The mother of every person gives him birth according to his true nature. It is subsequently his parents who make him a Jew or a Christian or a Magian. Had his parents been Muslim he would have also remained a Muslim. Every person to whom his mother gives birth (has two aspects of his life) ; when his mother gives birth Satan strikes him but it was not the case with Mary and her son (Jesus Christ).

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي الدَّرَاوَرْدِيَّ - عَنِ الْعَلاَءِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ كُلُّ إِنْسَانٍ تَلِدُهُ أُمُّهُ عَلَى الْفِطْرَةِ وَأَبَوَاهُ بَعْدُ يُهَوِّدَانِهِ وَيُنَصِّرَانِهِ وَيُمَجِّسَانِهِ فَإِنْ كَانَا مُسْلِمَيْنِ فَمُسْلِمٌ كُلُّ إِنْسَانٍ تَلِدُهُ أُمُّهُ يَلْكُزُهُ الشَّيْطَانُ فِي حِضْنَيْهِ إِلاَّ مَرْيَمَ وَابْنَهَا ‏" ‏ ‏.‏
