It is narrated from Hazrat Abu Qalabah. He says that when Iblis was declared accursed by Allah Almighty, he asked Allah Almighty for respite. So Allah Almighty granted him respite until the Day of Resurrection. Iblis said: By Your honor! I will remain in the belly or heart of the son of Adam as long as there is soul in him. Allah Almighty said: By My honor! As long as there is soul in him, I will not close the door of repentance for him.
