Hadith 133
Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Every child is born upon the natural disposition (fitrah), but his parents make him a Jew or a Christian, just as camels give birth to their young whole and sound. Do you find any among them that is mutilated?" The people asked: O Messenger of Allah! What is your opinion about a child who dies in infancy? The Prophet Muhammad (peace and blessings be upon him) replied: "Allah knows best what they would have done."
