Re-reading the answer to my question Going from "never prayed in my life" to my first prayer?, I encounter the importance of tashahhud. I'm embarrassed to admit it, but I haven't been doing tashahhud. After five months, I think it's no longer reasonable for me to use the excuse "...but I'm a new Muslim".
While other aspects of my prayer seem fine (comparable to the other women at mosque), there's two obstacles:
I'm brand new to Arabic.
I don't belong to a sect ("...just a Muslim"), and I don't intend to (as per Qur'an 6:159; and I perceive them mostly as an obstruction to submitting to Allah).
The Wikipedia page lists five different ones according to various sects [(a) Hanafi and Hanbali, (b) Maliki, (c) Shafii, (d) Ja'fari, and (e) Zaidi]. Basically, I want to avoid choosing one over the others. The attitude expressed in the question Is there any problem praying in the same way as Muslims from other sects? also gives me the impression I should avoid "choosing a side".
If I were to put my mind to it, I could memorize the Arabic (I can recite al Fatihah after all; and it seems I need to recite it in each rakaa, so at least 2+4+4+3+4=17 times per day, so I'd get used to it quickly). However, it seems different sects recite different tashahhud (though fairly similar in content) and I'm reluctant to single out one.
Question: Is there a sect-neutral tashahhud?
For example, could I just say the shahada instead? Or is there a version that the Prophet Muhammad is known to say?
