﴿ 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?”

(Do their minds command them to do this) denial, abuse and harm of Muhammad (pbuh). This was said as an attack against them, (or are they) they are indeed (an outrageous folk) disbelievers and arrogant folk with regard to transgressing against Allah?
