Yes, he has passed away but he was the head of the Wahhabiyya in Damascus. He was once accused of tampering with the words of Imam al-Nawawi in his Kitab al Adhkar, but when he was asked directly by Shaykh Mahmud Saeed Mamduh if he had done this - al-Arna'ut replied by blaiming the Riyadh based Wahhabi printers for tampering with it instead! Arna'uts hand written reply is printed in the back of Shaykh Mahmud' book on Tawassul: Raf al-Minara (which refuted most of the contemporary Wahhabi lies on this issue) in nearly 400 pages.
