Sahih Muslim | Book 33 | Hadith Number 6428
Narrated by Abu Huraira
Abu Huraira reported from Allah's Messenger (may peace be upom him) many ahadith and one amongst them is that he is reported to have said: An infant is born according to his (true) nature. It is his parents Who make him a Jew, a Christian, just as a she-camel gives birth to its young ones. Do you find any deficiency in their limbs? You cut their ears (i.e. after birth). They (the Companions of the Holy Prophet) said: What is your opinion about him who dies in infancy? Thereupon Allah's Apostle (may peace be upon him) said: It is Allah alone Who knows best what they would be doing.
