Will the child of zina enter Paradise, and if not, what is the wisdom behind that?

The child born out of wedlock bears no sin or transgression, and is born upon the fitra (primordial nature), as the Prophet, peace and blessings be upon him, said: "Every child is born upon the fitra." He will be held accountable for his own deeds, not for the actions of his parents, as Allah the Almighty says: "And no bearer of burdens will bear the burden of another." If he reaches the age of accountability and dies, he will be among the people of Paradise or Hell according to his deeds. The hadith (definition) "The child of zina (fornication/adultery) will not enter Paradise" is unsound and fabricated.
