Does magic or the evil eye affect one's provision, and what is the solution and cure if that is the case and I do not know who is responsible?

The evil eye is real and has an impact on the afflicted, which may lead to death or destruction of property. The Prophet, peace and blessings be upon him, said: "The evil eye can send a man to his grave and a camel to its pot," and he also said: "The evil eye is real. If anything could precede divine decree, the evil eye would."
