Aweakness of all of the muslim empire, including the ottomans, the mughals, and the safavids, was that they all were focused on land acquisition and did not develop their navies in order to control the seas.

This is true, not having a navy has shown itself to be a weakness of many nations/civilizations in the past. And there are also good reasons why this is so. Not having a navy strongly impacts a civilizations ability to maneuver around certain points and go around them. It also limits the ability to trade with other natons. Not to mention the additional value of having the firepower of ships (those that had cannons later on at least).
