There is another Hadeeth from the Prophet (SAWA) stating: My self and Ali were created from one Noor أنا وعلي ٬تم نور واحد.
Please specify which Hadeeth is meant in your question.
There are many different hadith that are considered hadith qudsi (that is, telling us directly what God says, but not as part of the Qur'anic revelation).
Some of these hadith are shared between Sunnis and Shi'is, and some are specifically Sunni, and some are specifically Shi'i.
As mentioned in the previous answer, each one can be evaluated individually with respect to its authenticity.
Hadeeth Qudsi is narrated in Sunni and Shia books. Our Ulama study the content and the chain of narrators before giving their opinion about the authenticity of it.
We have books on Hadeeth Qudsi compiled by Shia Ulama as well as Sunni Ulama.
