At the end of Al-Mansur's reign, the Ottoman governor of Tlemcen attacked the oasis of Figuig and tried to impose taxes on close areas there. As a result, the Ottoman Sultan sent a letter to the Pasha of Algeria to remind him that the oasis belonged to the honorable Sultanate in accordance with the agreements with sultans Murad III and Mehmed III. He alerted him from any move that could lead to dire consequences.
