Inshallah, I will go to Iran again in May. I intend to pray in the mosques there and I would like to fit in better with my (presumably mostly Shia) sisters when doing so.
Question: How can a new Muslim fit in when praying in a mosque in Iran?
I'm seeking beginner-level ("do this and you'll be fine") instructions for being able to pray in Iranian mosques without complications. I want to stay away from the Shia-Sunni politics.
I learned to pray Hanafi, Sunni style, although it's now a hodge-podge of different styles. I have no strong preference just as long as I pray to Allah. I only started praying less than a year ago, and my prayer is imperfect, but I've been improving over time.
I prayed once before in a mosque in Iran (my first time ever in a mosque; my only time in Iran), and the lady next to me just said "copy me", so I did.
From what I understand, the differences I need to know about are:
There's a stone, although I'm not really sure what to do with it.
Shia Muslims pray with their hands by their sides. (As per What are the major differences between Sunni and Shi'i prayer?)
These two items are possibly enough to be able to fit in, but I'm unsure if I'm missing something. I'm not going to be capable of reciting Arabic, other than al Fatiha (and al Humazah now) and the tashahhud.
Part of the motivation behind this question is recently being "corrected" for praying Hanafi style in a Tunis mosque, which I believe predominately follows the Maliki madhhab. I know she meant well, but it's something I'd rather avoid happening again. I want to just fit in and worship Allah without such issues arising.
