Sufism throughout the second half of the 20th century has been an influential current in the Sunni religious practises, particularly in Damascus. The largest women-only and girls-only Muslim movement in the world happens to be Sufi-oriented and is based in Damascus, led by Munira al-Qubaysi. Syrian Sufism has its stronghold in urban regions such as Damascus, where it also established political movements such as Zayd, with the help of a series of mosques, and clergy such as Abd al-Ghani al-Nabulsi, Sa'id Hawwa, Abd al-Rahman al-Shaghouri and Muhammad al-Yaqoubi.
