How can a Muslim woman, who has been committed to her religious duties for eight years, be saved from the continuous fear of death and the hereafter that accompanies her?

Remembering death and the Hereafter is a religious requirement, based on the Prophet Muhammad's (peace be upon him) saying: "Increase your remembrance of the destroyer of pleasures," meaning: death. However, this remembrance must be in moderation, so that it does not dominate one's thoughts and hinder them from performing their duties or lead to obsessive thoughts, as that is from the wiles of Satan. Satan may push a person to excess in acts of worship until he deviates from the path of moderation. Therefore, one must not surrender to Satan's whisperings but rather seek refuge in Allah Almighty and continue in His obedience.
