Assalamu alailum..

I'm Abdur Raquib from Bangaladesh.

My question is "what was Prophet (s) made of actually?" "soil or Light?"

It is my understanding that the prophets in the Quran were humans, but for clarity, your local religious leader should be consulted in this matter.

Islam teaches that God has sent prophets to humanity, in different times and places, to communicate His message. Since the beginning of time, God has sent His guidance through these chosen people. They were human beings who taught the people around them about faith in One Almighty God, and how to walk on the path of righteousness. Some prophets also revealed God's Word through books of revelation (https://www.thoughtco.com/books-of-revelation-2004108).
