I have some lovely postcards - cherished - of the Hagia Sophia - sent to me by Dr. Yusuf Ziya Kavakci years ago. Such a magnificent edifice, albeit I have never had the opportunity to step foot into the building.
There does seem to be a trend for re-purposing of worship spaces. I have a friend in Birmingham, UK who attends a masjid which was formerly a church.
It was good to see you post on this site. I was actively involved, several years ago - and still treasure the handwritten letter received from respected. Dr. Shabbir.
