Surah 39. Az-Zumar, Ayah 43

This is the meaning of the particle am in this context (Zamakhshari), implying that despite all the evidence of God's almightiness, many people tend to disregard it.

I.e., intercessors who could act as such independently of God's permission - an assumption which the Qur'an categorically denies (see surah {10}, note [7]).

A reference to the adoration of dead saints or their tombs or relics, as well as of inanimate representations of saints, of imaginary deities, etc.

Let alone worship, men should not rely upon any power or person other than Allah to help them out or intercede for them. When it is idols, they are poor lifeless things which have obviously neither power nor intelligence. But even prophets or saints or heroes have no power to intercede except as Allah wills and permits. See next note.
