This hadeeth comes under the following chapter: EVERYONE IS BORN ACCORDING TO HIS TRUE NATURE AND THE COMMAND PERTAINING TO THE DEMISE OF THE CHILDREN OF THE INFIDELS AND OF THE CHILDREN OF THE MUSLIMS
Abu Huraira reported from Allaah's Messenger (sallAllaahu alayhi wa sallam) 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 Prophet) said: What is your opinion about him who dies in infancy? Thereupon Allaah's Prophet (sallAllaahu alayhi wa sallam) said: It is Allaah alone Who knows best what they would be doing.
