Starting Off Salah With Rafa Yadayn
Ibadis are remnants of Khawarij movement who as far as I know, abrogated my Sunnah practices later on to protect their political interests. It’s no surprise if they don’t do that and also its better to first ask the relevant group as to why they don’t do it without bringing into question the ijma and tawatur. The way Ismaelis changed Salah later at some stage, Ibadis must’ve made some amendments later at some stage.
