When visiting Iran, I noticed that people performed taslim differently than I'm used to. Basically, what I'm used to is:
Look right and say assalamu alaikum wa rahmat Allah.
Look left and say assalamu alaikum wa rahmat Allah.
This is as indicated on the Wikipedia page.
What I saw in Iran was something along the lines of holding one's right hand up and moving it up and down, looking right and left, and saying a longer version of assalamu alaikum wa rahmat Allah three times.
I'm hoping to clarify what's going on here.
Question: How do Shias perform the taslim (final salam) in prayer?
