Yahya related to me from Malik from Abu'z Zinad from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "Every child is born on the fitra and it is his parents who make him a jew or a christian. Just as a camel is born whole - do you perceive any defect?" They said, "Messenger of Allah, what happens to people who die when they are (very) young?" He said, "Allah knows best what they used to do."
