﴿ ثُمَّ تَوَلَّوْا۟ عَنْهُ وَقَالُوا۟ مُعَلَّمٌۭ مَّجْنُونٌ ﴾

“whereupon they turned their backs on him and said, “Taught [by others] is he, a madman”?”

And they had turned away from him) and they turned away from believing in him (and said: One taught (by others)) i.e. Muhammad is taught by Jabr and Yasar, (a madman) who is bewitched?
