﴿ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَن ضَلَّ عَن سَبِيلِهِۦ وَهُوَ أَعْلَمُ بِٱلْمُهْتَدِينَ ﴾

“Verily, thy Sustainer alone is fully aware as to who has strayed from His path, Just as He alone is fully aware of those who have found the right way.”

‘Do not give in to the deniers of truth’ means that the words of those who deny the truth are not worthy of acceptance. On the one hand, there is the upholder of Truth, who has taken his stand by virtue of reasoning. There is no contradiction between his words and his actions. On the other hand, there are his opponents who are of low character and have nothing to their credit except for false utterances. The missionary of Truth relies on Truth, whereas his opponents rely on their material status. The missionary of Truth is a follower of principles, unlike his opponents who are unprincipled, and whose views are highly inconsistent. For one who has a sound mind, this difference is enough to show who is on the right path and who is not.
