﴿ أَمْ تَأْمُرُهُمْ أَحْلَٰمُهُم بِهَٰذَآ ۚ أَمْ هُمْ قَوْمٌۭ طَاغُونَ ﴾

“Is it their minds that bid them [to take] this [attitude] - or are they [simply] people filled with overweening arrogance?”

Or do their faculties of understanding prompt them to say this? their saying to him you are either a sorcerer a poet a soothsayer or a madman in other words they do not in reality prompt them to say this. Or am in effect means bal ‘rather’ are they a rebellious lot? because of their obstinacy.
