Verse 125

ٱدْعُ إِلَىٰ سَبِيلِ رَبِّكَ بِٱلْحِكْمَةِ وَٱلْمَوْعِظَةِ ٱلْحَسَنَةِ وَجَـٰدِلْهُم بِٱلَّتِى هِىَ أَحْسَنُ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَن ضَلَّ عَن سَبِيلِهِۦ وَهُوَ أَعْلَمُ بِٱلْمُهْتَدِينَ

Invite to the path of your Lord with wisdom and kind enlightenment, and debate them in the best possible manner. Indeed your Lord knows best who has strayed from His path and knows best about the guided ones.
