I never saw a Shii saying ya Allah.
I have a question for some members here. Is it shirk to say " peace be upon you, rasullulah" ?
Nobody ever said that's shirk, and Deobandies have a very good understanding of Tawassul (the shari3i one not the shirki one). You have to understand the language of the Arabs to understand that merely saying Ya Rasulallah etc. is not shirk:

You probably mean the likes of IBN OMAR with some since it is AUTHENTICALLY reported from some sahaba that they said as-salamu' 3ala An-Nabiyy (SAWS) after the Prophet's (SAWS) demise. In any case, both version (as-salamu 'alayki and 'ala) are right and authentic so it has nothing to do with extremism. What is extreme is to be ignorant of the Arab language like the Rafidah and to mix up everything, not understanding that in the Arab language one can address someone directly (like Rasulullah) but in a form of remembrance NOT prayer to him, secondly the tashahhud is a prayer FOR Prophet Muhammad not TO Prophet Muhammad (and angels deliver the Salam), so in any case it is not praying TO him and asking your needs FROM his as Rafidah and some extremist Sufis do.
Imam al-Bukhari related in his Adab al-Mufrad (no. 964):
Abu Nu’aym related to us who said that Sufyan related to us from Abu Ishaq from Abdar Rahman ibn Sa’d, who said:
Ibn Umar had numbness in his leg, whereupon a man said to him:
“Remember the most beloved of people to you”, so he said: “Ya Muhammad”
If you weaken it, please don't come with Al-Albani's criteria, but with the commentatory of scholars of the past.
I also found this:

Even if the authenticity of the narration is proven, again the narration is not problematic at all and has NOTHING to do what Rafidah and other extremist sects do. Think about it:
1. Did Ibn Omar PRAY to the Prophet?! NO, he remembered him (in Arabic we remember ANYONE, dead or alive by saying YA FULAN ... WAA FULAN etc.)
2. Did Ibn Omar asked the Prophet for ANY of his needs, like to be cured?1 Again, NO. He just reminded himself of a VERY dear person i.e. the Messenger of Allah (SAWS).
So doesn't matter if the hadith is sahih or dha3if since it has nothing to do with praying to other than Allah like Rafidah and extremist Sufis do when they address the Prophet directly ASKING him (praying to him) for ALL their needs.
See, when I feel sad (or feel pain) I remember the most beloved person to me, which is RASULULLAH (SAWS), I do the same thing as Ibn Omar, nothing wrong with it.
