How can one overcome feelings of dissatisfaction, envy, and constant comparison with others, especially when the soul yearns for what they possess, despite the abundance of blessings and good in the questioner's life?

The problem of discontent with what Allah Almighty has apportioned, and its remedy, lies in the certainty that Allah's choice for His servant is better than the servant's choice for himself, and that Allah knows best what is in his interests, and in not objecting to divine decree. For contentment with Allah as Lord means contentment with all His actions and His management of affairs, as the believer knows that all good is in Allah's hand. Contentment is Allah's greatest door, the paradise of this world, and the resting place of the gnostics, and it results from Allah's contentment with His servant. Contentment is facilitated by the servant's knowledge of his own weakness and helplessness, and his knowledge that both blessings and afflictions are by prior decree, and that each contains good for him, and that Allah knows best what is in the servant's interest, and that the servant is submitted to Allah. Furthermore, contentment comes from having a good opinion of Allah and not accusing Him in His judgments and decrees. The servant should focus his efforts on gaining Allah's pleasure and on what He has prepared for His righteous servants in the Hereafter, and he should seek Allah's help and supplicate Him to grant him contentment with His decree and destiny.
