Concept Of SHIRK
Shirk is to make others partner in the Being, creation and administration of God. The work under the forces of physical laws is a human domain. We ask people to help us with their knowledge and skills. This isn’t shirk b The man in the court of the prophet Suleiman knew a law, as Qur’an stated, Illm minal kitab, it was a method to teleport things. Science is still working on it and may discover it once again. The claim you made about saints needs validation. We are not told in the Quran nor in hadith that sainthood is a special designation which give special powers to a person and it gets multiplied after death. This whole idea has no validation. If a person has some extraordinary skill, it is a science. The wonders of science are miracles for those who do not know the science, the same is the case with those who do not know the laws known to the man in the court of Sulaiman. This doesn’t imply he could do it after his death too.
