Surah Az-Zukhruf — Ayah 37 (43:37)
وَإِنَّهُمۡ لَيَصُدُّونَهُمۡ عَنِ ٱلسَّبِيلِ وَيَحۡسَبُونَ أَنَّهُم مُّهۡتَدُونَ ٣٧
English translation (Saheeh International)
And indeed, they [i.e., the devils] avert them from the way [of guidance] while they think that they are [rightly] guided
Brief commentary
Indeed, these satan companions who have been set upon those who turn away from the Qur’ān, prevent them from the religion of Allah. They are unable to fulfil His commands and refrain from things He has not allowed; they think that they are guided to the truth and so they do not repent from their deviance.
