CEVAP:

As part of another reform in 1934, wearing all types of religious attire for ordinary people was restricted to mosques in order to make religious symbols invisible in daily life. This ban had an exception, though, for those who were the clerical leaders of different religious communities existing in the population of the country. Thus, religious attire in daily life and in occasions that are not religious was deemed legal only to one person for each religion, to whoever is the spiritual leader of it.
