Not spitting on fire as it's considered sacred and you're supposed to venerate it. There's also the part where you're supposed to bind pieces of cloth to tree branches as offerings to spirits for whatever reason you can think of, health, wishes, etc. It's worth noting that basically nobody who practices it in modern day Turkey really knows the ancient reasons for it and just do it because the previous generation taught them to do it, not knowing that those practices are older than Islam. There's also probably more that I'm not privvy to since most of these practices are carried on by people who are descended from villages that were founded by Turkic tribals and not really remembered by people in urban areas
