«وَإِنَّهُمْ لَيَصُدُّونَهُمْ عَنِ السَّبِيلِ وَيَحْسَبُونَ أَنَّهُمْ مُهْتَدُونَ»
“They certainly turn them away from the path, while the latter suppose that they are rightly guided.” (al-Zukhruf 43:37)
The preceding verse speaks of a devil assigned as a companion (43:36). Accordingly, the agents preventing people from the path are understood as the devils, while the people being misled imagine themselves guided.
Treating every pronoun as if it referred to the same party would distort the account. Correct interpretation identifies distinct referents from the discourse while preserving the transmitted pronoun forms.
