Brother Dawud, I believe that people who believe in Wahdatul Wujud are out of the fold of Islam, So if the Mufti you are going to believes in Wahdatul Wujud then can't you see why, I worry about you brother. I'm a former Shia Brother when I became Sunni, I followed the Maliki Madhab, I'm now Following Ahle Hadith, I have a Ahle Hadith Shaykh who I will be studying with soon Insha'Allah. Why not study with Ahle Hadith/Salafi Shaykh???
