Will Abraham's father enter paradise or not? How do we determine where someone will end up after they die?

Summary:

- Abraham's father was a statue-maker. He was not a monotheist. However, you cannot make any declarations as to where he will end up.

- It will be decided on the Day of Judgement who will enter paradise or not. You cannot declare anybody to be paradise-bound or hellbound before that. It is up to God where he wants to send people.

- Some people worship all their lives but God does not accept their worship. On the other hand, someone could be a sinner but because they kissed a saint's feet just once, God will send them to paradise.

'God is the sole owner of the Day of Judgement.' - Koran 1:4

'On that Day, salvation will be granted through God's bounty.' - Prophetic Tradition

You have no rights on the Day of Judgement. All rights belong to God.
