Is the deprivation of sustenance and the delay in employment despite work competence a result of previous sins or magic?

We do not have a specific reason for what happened, but we advise you of the following: Ruqyah (definition) (Islamic exorcism/healing) is permissible for a Muslim whether they are afflicted or not, and supplication is never wasted. So, if what you desired did not materialize, do not despair, for Allah might have chosen what is best for you. Do not despair of finding a job; strive by permissible means and avoid forbidden ones. If what you did was before puberty, then you are not held accountable, as the Prophet, peace and blessings be upon him, said: "The pen has been lifted from three."
