Every child is born on Islam, but his parents make him a Jew and a Christian, just as a beast is born whole. Do you find some among them (born) maimed? The people asked : Messenger of Allah! What do you think about the one who died while he was young? He replied : Allah knows best what he was going to do. (Using translation from Abū Dāʾūd 4714)   

قَالَ رَسُولُ اللهِ ﷺ كُلُّ مَوْلُودٍ يُولَدُ عَلَى الْفِطْرَةِ فَأَبَوَاهُ يُهَوِّدَانِهِ وَيُنَصِّرَانِهِ كَمَا تَنَاتَجُ الْإِبِلُ مِنْ بَهِيمَةٍ جَمْعَاءَ هَلْ تُحِسُّ فِيهَا مِنْ جَدْعَاءَ؟ قَالُوا يَا رَسُولُ اللهِ أَفَرَأَيْتَ مَنْ يَمُوتُ وَهُوَ صَغِيرٌ؟ قَالَ اللهُ أَعْلَمُ بِمَا كَانُوا عَامِلِينَ  

[Machine] The Messenger of Allah ﷺ said: "There is no newborn among the children of Adam except that he is born upon the fitrah (natural disposition), until his parents make him Jewish, Christian, or Magian, just as an animal gives birth to a perfect offspring. Do you find any among them imperfect? Then Abu Hurairah recited: 'The fitrah (natural disposition) of Allah upon which He has created [all] people. No change should there be in the creation of Allah. That is the correct religion, but most of the people do not know.'" [Quran 30:30]  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَا مِنْ مَوْلُودٍ فِي بَنِي آدَمَ إِلَّا يُولَدُ عَلَى الْفِطْرَةِ حَتَّى يَكُونَ أَبَوَاهُ يُهَوِّدَانِهِ أَوْ يُنَصِّرَانِهِ أَوْ يُمَجِّسَانِهِ كَمَا تُنْتَجُ الْبَهِيمَةُ بَهِيمَةً جَمْعَاءَ هَلْ تُحِسُّونَ فِيهَا مِنْ جَدْعَاءَ؟ ثُمَّ يَقُولُ أَبُو هُرَيْرَةَ وَاقْرَءُوا إِنْ شِئْتُمْ {فِطْرَةَ اللهِ الَّتِي فَطَرَ النَّاسَ عَلَيْهَا لَا تَبْدِيلَ لِخَلْقِ اللهِ ذَلِكَ الدِّينُ الْقَيِّمُ وَلَكِنَّ أَكْثَرَ النَّاسِ لَا يَعْلَمُونَ} [الروم 30]  

Messenger of Allah ﷺ said, "No child is born but has the Islamic Faith, but its parents turn it into a Jew or a Christian. It is as you help the animals give birth. Do you find among their offspring a mutilated one before you mutilate them yourself?" The people said, "O Messenger of Allah ﷺ! What do you think about those (of them) who die young?" The Prophet ﷺ said, "Allah knows what they would have done (were they to live)." (Using translation from Bukhārī 6599)   

قَالَ رَسُولُ اللهِ ﷺ مَنْ يُولَدُ يُولَدُ عَلَى هَذِهِ الْفِطْرَةِ فَأَبَوَاهُ يُهَوِّدَانِهِ وَيُنَصِّرَانِهِ كَمَا تُنْتَجُ الْبَهِيمَةُ فَهَلْ تَجِدُونَ فِيهَا مِنْ جَدْعَاءَ حَتَّى تَكُونُوا أَنْتُمْ تَجْدَعُونَهَا؟ قَالُوا يَا رَسُولُ اللهِ أَفَرَأَيْتَ مَنْ يَمُوتُ وَهُوَ صَغِيرٌ؟ قَالَ اللهُ أَعْلَمُ بِمَا كَانُوا عَامِلِينَ  

[Machine] The Messenger of Allah ﷺ said, "There is no newborn except that they are born upon this religion until their tongue becomes apparent, and then their parents either make them into Jews, or Christians, or polytheists, or magicians." They asked, "O Messenger of Allah, what about those who came before that?" Meaning, those who have died. He said, "Allah knows best what they were doing."  

قَالَ رَسُولُ اللهِ ﷺ لَيْسَ مِنْ مَوْلُودٍ يُولَدُ إِلَّا عَلَى هَذِهِ الْمِلَّةِ حَتَّى يُبِينَ عَنْهُ لِسَانُهُ فَأَبَوَاهُ يُهَوِّدَانِهِ أَوْ يُنَصِّرَانِهِ أَوْ يُشَرِّكَانِهِ أَوْ يُمَجِّسَانِهِ قَالَ فَقَالُوا يَا رَسُولَ اللهِ فَكَيْفَ بِمَنْ كَانَ قَبْلَ ذَلِكَ؟ يَعْنِي مَاتَ قَالَ اللهُ أَعْلَمُ بِمَا كَانُوا عَامِلِينَ  

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). (Using translation from Muslim 2659a)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ كُلُّ إِنْسَانٍ تَلِدُهُ أُمُّهُ عَلَى الْفِطْرَةِ أَبَوَاهُ يُهَوِّدَانِهِ أَوْ يُنَصِّرَانِهِ أَوْ يُمَجِّسَانِهِ فَإِنْ كَانَا مُسْلِمَيْنِ فَمُسْلِمٌ كُلُّ إِنْسَانٍ تَلِدُهُ أُمُّهُ يَلْكُزُهُ الشَّيْطَانُ فِي حِضْنَيْهِ إِلَّا مَرْيَمَ وَابْنَهَا  

[Machine] Narrated by the Prophet ﷺ , "Every newborn is born on the Fitrah (natural inclination towards goodness) until his parents convert him to Judaism or Christianity or change his nature. Al-Shafi'i, in the old narration of Abu 'Abd al-Rahman al-Baghdadi, stated that the Prophet ﷺ said, 'Every newborn is born on the Fitrah (the natural inclination upon which Allah has created mankind), and it is the parents who turn them into one of the two beliefs: faith or disbelief.' They have no choice in themselves, and the judgment is only for their parents. So, as their parents were on the day they were born, they are either believers, so they are judged by their faith, or disbelievers, so they are judged by their disbelief."  

عَنِ النَّبِيِّ ﷺ قَالَ كُلُّ مَوْلُودٍ يُولَدُ عَلَى الْفِطْرَةِ حَتَّى يُعْرِبَ عَنْ نَفْسِهِ زَادَ فِيهِ غَيْرُهُ فَأَبَوَاهُ يُهَوِّدَانِهِ وَيُنَصِّرَانِهِ قَالَ الشَّافِعِيُّ فِي الْقَدِيمِ فِي رِوَايَةِ أَبِي عَبْدِ الرَّحْمَنِ الْبَغْدَادِيِّ عَنْهُ قَوْلُ النَّبِيِّ ﷺ كُلُّ مَوْلُودٍ يُولَدُ عَلَى الْفِطْرَةِ الَّتِي فَطَرَ اللهُ عَلَيْهَا الْخَلْقَ فَجَعَلَهُمْ رَسُولُ اللهِ ﷺ مَا لَمْ يُفْصِحُوا بِالْقَوْلِ فَيَخْتَارُوا أَحَدَ الْقَوْلَيْنِ؛ الْإِيمَانَ أَوِ الْكُفْرَ لَا حُكْمَ لَهُمْ فِي أَنْفُسِهِمْ إِنَّمَا الْحُكْمُ لَهُمْ بِآبَائِهِمْ فَمَا كَانَ آبَاؤُهُمْ يَوْمَ يُولَدُونَ فَهُوَ بِحَالِهِ إِمَّا مُؤْمِنٌ فَعَلَى إِيمَانِهِ أَوْ كَافِرٌ فَعَلَى كُفْرِهِ  

In our opinion it means that covenant which Allah had taken in the loins of their fathers when He said : “Am I not your Lord? They said: Yes. (Using translation from Abū Dāʾūd 4716)   

سَمِعْتُ حَمَّادَ بْنَ سَلَمَةَ يُفَسِّرُ حَدِيثَ كُلُّ مَوْلُودٍ يُولَدُ عَلَى الْفِطْرَةِ قَالَ هَذَا عِنْدَنَا حَيْثُ أَخَذَ اللهُ ﷻ عَلَيْهِمُ الْعَهْدَ فِي أَصْلَابِ آبَائِهِمْ حَيْثُ قَالَ {أَلَسْتُ بِرَبِّكُمْ قَالُوا بَلَى} [الأعراف 172]  

[Machine] That the messenger of Allah ﷺ said: "Every child is born on the Fitrah (natural inclination towards Islam), then his parents make him Jewish, Christian or Magian." Al-Awza'i said: "They do not remove him from the knowledge of Allah, and they will ultimately return to the knowledge of Allah."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ كُلُّ مَوْلُودٍ يُولَدُ عَلَى الْفِطْرَةِ فَأَبَوَاهُ يُهَوِّدَانِهِ وَيُنَصِّرَانِهِ وَيُمَجِّسَانِهِ قَالَ الْأَوْزَاعِيُّ لَا يُخْرِجَانِهِ مِنْ عِلْمِ اللهِ وَإِلَى عِلْمِ اللهِ يَصِيرُونَ
