What is the reason for continuous lack of success at work? Is it envy (hasad)? And what is the remedy, especially with the recitation of Ruqyah and the seeing of true visions?

This world is a realm of trials and tests. What befalls a person, such as failure, may be a consequence of their shortcomings in their duty to Allah, just as a servant may be deprived of provision due to a sin they have committed. A Muslim must strive to acquire lawful means of sustenance and beware of following the footsteps of Satan and succumbing to pessimism. Among the most comforting things for the heart are contentment with Allah's decree and destiny, diligently pursuing means, and relying upon Allah.
