It is a very beautiful mosque built on behalf of Abdulvehhab Efendi, one of the last women of the Ottoman Empire, who was a student of the great scholar es-Sayyid Fehim Efendi of Van and later es-Sayyid Abdulhakim Arvasi. It used to be an old lodge that was left in a very ruined state, it was revived and rebuilt in recent years. May Allah be pleased with those who do.Monday August 3 Beykoz 2020 11 53
