Optimizing default middleware behavior

I have the following middleware:

class OwnerOrAdmin
{
    public function handle($request, Closure $next)
    {
        $user = \Auth::user();
        $postId = $request->route('post');
        $post = $user->posts->find($postId);

        if ($user->id == 1 || (!is_null($post) && $post->user_id == $user->id)) {
            return $next($request);
        }

        return redirect()->route('post.index')
                ->with(['status' => 'danger', 'mensagem' => 'Este post não te pertence!']);
    }
}

Basically this check if the user who will edit a post is Admin (id = 1) or if this is the owner of the post.

But in my controller I have to repeat practically the same query to the bank:

public function edit($id)
{
    $post = Post::find($id);

    return view('painel.post.cad-edit', compact('post'));
}

Would it be possible to pass this value to the controller as a middleware return?
