Селим I
After Chelebi Khalifa’s death, the power was passed to his son-in-law, Sunbul Efendi. He was considered a very spiritual man that saved the Koca Mustafa Pasha Mosque. According to the miraculous account, the new sultan Selim I, was suspicious of the Khalwati order and wanted to destroy its "tekke". Selim I sent workers to tear down the "tekke", but an angry Sunbul Efendi turned them away. Hearing this, Selim I went down there himself only to see hundreds of silent dervishes gathered around Shaykh Sunbul dressed with his "khirqa". Selim was astonished by Sunbul’s spiritual power and canceled the plans to destroy the "tekke".
