If the body of the first deceased has disintegrated, this is permissible. but if the body is still there, it shouldn’t be used or opened.

Is it allowed to bury someone in a grave which has already been used ( had a deadbody in it). Jazak’Allah.

We know that it is highly desirable to hasten the burial. I also read that Allah will forgive the sins of the dead if more person pray salat at janaza.so how long can we delay the burial for more person to come?can we delay it for 1 day?

After death does the body of the deceased person feel pain e.g while giving it gusul or transporting the body to the grave?
