Are Shia / Shi'aa related to Islam in any way?
In the name of Allah, Most Gracious, Most Merciful
Assalaamu `alaykum waRahmatullahi Wabarakatoh
Firstly, hereunder are the criteria for declaring someone a non-Muslim:
When a person openly calls himself a non-Muslim, i.e. he accepts that he is a Christian, Jew, Hindu, etc. When a person negates, through his words or actions, something unanimously proven through Quran and Hadith. He will not be regarded a Muslim even though he claims to be one.

Secondly, although the Shias claim that they are Muslims, most of them have beliefs that negate the clear cut principles of Islam. Some of these beliefs are listed below:
Aaapke Masaail aur Unka Hal Vol:1 Pg:188 (Maktabah Bayyinat)
Thereafter, Shias are categorised into three groups in regards to the ruling they fall under:
It is not permissible to have inter-marriages with such Shias, Janazah Salaah will not be performed upon their deceased, the meat from the animals slaughtered by them will not be halaal and all other laws confined to Muslims will not apply to them.
The laws confined to Muslims will apply on them, but it will not be advisable to have inter-marriages with them.
As a matter of precaution, inter-marriages with them will not be permissible and the meat from the animals slaughtered by them will not be halaal.
Jawaahirul Fiqh Vol:1 Pg:59-63 (Maktabah Darul Uloom Karachi)
As far as ties with Shias are concerned, it is not permissible to have close friendship with them. However, Islam encourages Muslims to have good conduct with them, and show good character.
And Allah knows best
