Surah Al-Kahf — Ayah 56 (18:56)
وَمَا نُرۡسِلُ ٱلۡمُرۡسَلِينَ إِلَّا مُبَشِّرِينَ وَمُنذِرِينَۚ وَيُجَٰدِلُ ٱلَّذِينَ كَفَرُواْ بِٱلۡبَٰطِلِ لِيُدۡحِضُواْ بِهِ ٱلۡحَقَّۖ وَٱتَّخَذُوٓاْ ءَايَٰتِي وَمَآ أُنذِرُواْ هُزُوٗا ٥٦
English translation (Saheeh International)
And We send not the messengers except as bringers of good tidings and warners. And those who disbelieve dispute by [using] falsehood to [attempt to] invalidate thereby the truth and have taken My verses, and that of which they are warned, in ridicule.
Brief commentary
I do not send any of Our Messengers except to give good news to the people of faith and obedience and to warn the people of disbelief and disobedience. They do not have the authority to make hearts accept the guidance. Those who disbelieved in Allah dispute with the Messengers despite their having clear proof, in an attempt to use their falsehood to remove the truth that was sent down to Muhammad (peace be upon him). They made the Qur’ān and what they were warned of a joke and mockery.
