Hadith #394
Arabic Text
وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَا مِنْ مَوْلُودٍ يُولَدُ إِلَّا عَلَى هَذِهِ الْفِطْرَةِ فَأَبَوَاهُ يُهَوِّدَانِهِ وَيُنَصِّرَانِهِ كَمَا تُنْتِجُونَ الْإِبِلَ فَهَلْ تَجِدُونَ فِيهَا جَدْعَاءَ حَتَّى تَكُونُوا أَنْتُمْ تَجْدَعُونَهَا قَالُوا يَا رَسُولَ اللَّهِ أَفَرَأَيْتَ مَنْ يَمُوتُ وَهُوَ صَغِيرٌ قَالَ اللَّهُ أَعْلَمُ بِمَا كَانُوا عَامِلِينَ
English Translation
the Messenger of Allah ﷺ said: 'No child is born except upon the fitrah (natural disposition). Then his parents make him a Jew or a Christian, just as you produce an animal: do you find any born mutilated before you mutilate them?' They said: 'O Messenger of Allah, what about those who die young?' He said: 'Allah knows best what they would have done.'
