Are the problems that occur after Salatul-Istikharah and the cessation of work a tribulation from Allah or a mistake on the part of the supplicant?

This world is a realm of trial and test, through which Allah tests His servants with calamities and blessings to see who is grateful and who is ungrateful. It is advised to seek permissible work to earn lawful money, and there is no objection to returning to work with your brother if no other work is available. It is also advised to be patient, to rely on Allah, and to have good expectations of Him.
