What we see in the Koran is what we see in the Old testament.
God is compassionate and merciful but.....
The prophets seek to apply conditions to God's Love.
They fear that sinful humanity will not do God's will without the threat of punishment.
This attitude results in prophecies of Judgment - the End Times and the Last Day.
None of this is true.
There is no punishment - no End Times, no Last Day.
There is no evidence that God punishes us at all so why would the situation be different after death?
In Indian Philosophy we are exhorted to non-violence ahimsa (harmlessness).
Why would God tell us to be non-violent if He was violent Himself?
Therefore, as there is no punishment, there can be no Hell (which is eternal punishment).
