How do I remove the fear of death caused by the whisperings of devils?

Remembering death and fearing it was the habit of the righteous and a recommendation of the Prophet, peace and blessings be upon him. It instills the fear of God, encourages good deeds, and promotes asceticism in worldly life.

However, fear should not lead to despair, hopelessness, or distraction from performing good deeds. The true believer combines fear with hope. Anxiety and fear stem from one of three things: fear of the future, worry about the present, or sorrow over the past.

To overcome this, one must entrust the future to God while preparing for it, deal with the present as it is, and forget the past which will not return. Salvation lies in believing in divine decree and destiny, being content with what God ordains, reciting the Quran, remembering God, associating with the righteous, and avoiding evil.
