The Caliphate ceases its expansions, and deploys some organized forces into the east. The Caliphate also goes back to steadily and safely (in terms of size, funding, and that jazz) building and developing its military to bring it up to former par. However, rather than putting all of its efforts towards that, it looks towards improving the roadways, and the security of these roadways, and railways are looked into as well.
The Caliphate also begins to primarily export silk, wine that they can't drink because allah said so, and to a smaller extent of the two, tea.
