The famous commentator Qatadah has given this same meaning of this verse.
( Ibn Jarir ).

 

( He would have tarried in its belly ) he would have remained in the belly of the fish ( till the day when they are raised ) from the graves;

He would have indeed remained inside its belly (the fish) till the Day of Resurrection.
