that there were 42 Bektashi tekkes in Albania. On the census Halvetis are not reported and are usually grouped under generalized "Muslims", although in public discourse they are frequently grouped with Bektashis. Halvetis are said to dislike both the dominance of mainline Sunnis in the generic "Muslim" community and the non-recognition of their sect's separate existence, but also the dominance of Bektashis in the Sufi scene. Besides the two most popular Dervish orders in Albania (Bektashis and Halvetis), there are three other significant Sufi orders: the Kadris (also known as "Kadris" or "Zinxhiris"), the Sadis and the Rufais. The Rufais originated in Iraq as the "Rifa'is", from the teachings of the jurist Ahmad ibn 'Ali al-Rifa'i. In the late 19th century there was a flourishing Rufai community around Gjakova, in Kosovo, which helped spread the sect in various parts of Albania. During the early years of the 20th century some Rufai tekkes became Bektashi. At the same time, in the same period the order spread to Tropoja, Tirana, Petrela and parts of Southern Albania. In Albania all of their tekkes were closed due to the banning of religion under Communism, but in Yugoslavia the order continued to operate major tekkes in Gjakova, Mitrovica, Skopje, Peja, Rahovec and Prizren. After the fall of Communism, the order reconstituted itself in Albania and opened a tekke in Tirana in 1998. The Sa'dis originated in Damascus and in Albania have a close relationship with the Bektashis. Both were favored by Ali Pasha and they looked after and venerated each other's holy places and tombs. There was a Sa'di tekke in Gjakova in 1600, and two Sa'di tekkes in Tepelena two centuries later, as well as some historical presence in Tropoja, Gjirokastër, Elbasan and Peza. In 1980 in Kosovo, there are 10 operating Sa'di tekkes.<ref>Elsie, Robert. Historical Dictionary of Albania. Pages 393–4.</ref> The Kadris first originated as a distinct sect in Istanbul in the 17th century, then were spread to the Balkans as the "Zindjiris" by Ali Baba of Crete, originally spreading from within the Bektashi community. There are Kadri tekkes in Tirana, Berat and Peqin, but the main center of the Kadris is Peshkopia in Diber County. In 1945 they were finally recognized as a distinct religious community; since the fall of Communism, they have reconstituted themselves and now have an operating tekke in Peshkopia.
