عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”كُلُّ مَوْلُودٍ يُولَدُ عَلَى الْفِطْرَةِ فَأَبَوَاهُ يُهَوِّدَانِهِ وَيُنَصِّرَانِهِ وَيُمَجِّسَانِهِ كَمَا تُنْتَجُ الْبَهِيمَةُ هَلْ تُحِسُّونَ فِيهَا مِنْ جَدْعَاءَ ثُمَّ يَقُولُ وَاقْرَءُوا إِنْ شِئْتُمْ {فِطْرَتَ اللَّهِ الَّتِي فَطَرَ النَّاسَ عَلَيْهَا لَا تَبْدِيلَ لِخَلْقِ اللَّهِ}“ [الروم: 30]
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Every child is born upon the natural religion, that is, the religion of Islam. Later, his parents make him a Jew, a Christian, or a Magian. This is just like an animal giving birth to a complete offspring—do you see any among them with a cut ear? If you want confirmation of this, then recite this verse: {فِطْرَتَ اللّٰہِ الَّتِیْ فَطَرَالنَّاسَ عَلَیْھَا لَا تَبْدِیْلَ لِخَلْقِ اللّٰہِ } (Adopt the nature of Allah, that is, this religion upon which He has created people; no one has the right to alter the creation of Allah.)
