But your people have denied it while it is the truth. Say, (6:66)

Almuntakhab Fi Tafsir Alquran Alkarim

Yet your people, thus still, deny the Quran, the truth guiding into all truth and deny themselves the knowledge, the wisdom and the spiritual light! Say to them: I am not entrusted to your care nor am I responsible for your ordinary pursuits of life

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(6:66) Your people have denied it even though it is the Truth. Say: "I am not a guardian over You. *43

But your people have denied it while it is the truth. Say, meaning

*43). A Prophet is neither required to compel People to see what they are not prepared to see nor to force into their hearts what they fail to comprehend. It is not a Prophet's task to chastise people for failing to see and comprehend the Truth. His task is merely to proclaim Truth as distinct from falsehood. If people fail thereafter to accept it, they will be overwhelmed by the very misfortunes against which that Prophet had warned.
