A reference to falsely deified saints or prophets and, particularly (in view of the context), to Jesus.
For an explanation of the Qur'anic concept of "intercession", see 10:3 - "There is none that could intercede with Him unless He grants leave therefore" - and the corresponding note [7]. - My interpolation, at the end of the above verse, of the words "that God is one and unique" is based on Razi's interpretation of this passage, implying that a mere oral "bearing witness to the truth" is useless if it is not the outcome of an inner awareness of God's oneness and uniqueness.
i.e., Jesus, Ezra, and the angels.
While idols and false gods have no power of intercession, persons like Jesus, who is falsely worshipped by his misguided followers, but who himself preached the Gospel of Unity with full understanding will have the power of intercession.
