Jund Filastin
After the caliph Sulayman ibn Abd al-Malik founded the city of Ramla next to Ludd, he designated it the capital, and most of Ludd's inhabitants were forced to settle there. In the 9th century, during Abbasid rule, Jund Filastin was the most fertile of Syria's districts, and contained at least twenty mosques, despite its small size.
