Al-Weeshi, who joined Contractors from Ahli in the close season, opened the scoring in the 62nd minute.
He scored on the rebound after Rami Rabie's shot was parried by Al-Gaish keeper into his path.
The combative striker doubled the lead eight minutes from time after converting a pinpoint cross.
Al-Weeshi left Ahli after failing to establish himself under Portuguese manager Manuel Jose.
He rarely featured for the Egyptian champions last term.
