Is the presence of ants on the body, the falling of objects, and the onset of sadness related to envy (Hasad)? If so, what is the remedy?

We have no knowledge of a relationship between ants and envy (hasad), nor whether the occurrence of envy is linked to the presence of such things. A person may be afflicted by envy at any time and in any place, but this should not be a cause for obsessions and excessive rumination that may lead to psychological illnesses. The Sharia has clarified means for preventing envy and treating it if it occurs.
