Is the ruling of declaring someone a disbeliever for all junior students of knowledge, or is it specific to the senior scholars?

Question:
Is the ruling of declaring someone a disbeliever for everyone, including junior students of knowledge, or is it specific to the senior scholars and judges?

Answer:
Whoever displays shirk (associating partners with Allah) by slaughtering for other than Allah or making a vow for other than Allah, in a clear and obvious manner—slaughtering for other than Allah, making a vow for other than Allah, calling for aid from other than Allah among the dead, or invoking the dead—this is apparent shirk. This is apparent shirk. So whoever hears this rules that he is a disbeliever and a mushrik (one who associates partners with Allah). As for the hidden matters, the hidden matters that require knowledge and insight, these are entrusted to the scholars of knowledge, entrusted to the scholars of knowledge.
