37وَإِنَّهُم لَيَصُدّونَهُم عَنِ السَّبيلِ وَيَحسَبونَ أَنَّهُم مُهتَدونَAli UnalSuch devils certainly bar them from the way (of truth). Yet they think (in themselves) that they are rightly guided.1Right or true guidance is the guidance of the Qur’ān. So, however rightly-guided those who follow other ways may regard themselves to be, they have, in reality, strayed far from the truth. The Qur’ān severely warns such people in 18: 103–104: Say: “Shall We inform you who are the greatest losers in respect of their deeds? Those whose endeavor has been wasted in this world (because it is directed only to this-worldly ends, and so it is bound to be wasted hereafter also) but who themselves reckon that they are doing good.” (See corresponding note 32.)
