I wanted to ask about the sunni practice of turning the head after Salam to conclude the salat. I’ve read that this is also mustahab for us Shi’a to do but I wanted to make sure, and how exactly would we do it? Is it after the 3 takbir? What do we say as we turn our heads?

If you are praying Jama’a, it is mustahab to slightly turn the head to the right (not face away from the Qiblah) and point your eyes to the right as you say the Taslim, then another Taslim the same way to your left if there is someone to your left, then say the 3 takbiras
