Surah An-Nahl, Verse 125

ٱدۡعُ إِلَىٰ سَبِيلِ رَبِّكَ بِٱلۡحِكۡمَةِ وَٱلۡمَوۡعِظَةِ ٱلۡحَسَنَةِۖ وَجَٰدِلۡهُم بِٱلَّتِي هِيَ أَحۡسَنُۚ إِنَّ رَبَّكَ هُوَ أَعۡلَمُ بِمَن ضَلَّ عَن سَبِيلِهِۦ وَهُوَ أَعۡلَمُ بِٱلۡمُهۡتَدِينَ١٢٥

ud'ʿu ilā sabīli rabbika bil-ḥik'mati wal-mawʿiẓati l-ḥasanati wajādil'hum bi-allatī hiya aḥsanu inna rabbaka huwa aʿlamu biman ḍalla ʿan sabīlihi wahuwa aʿlamu bil-muh'tadīna

Invite to the way of your Lord with wisdom and good instruction, and argue with them in a way that is best. Indeed, your Lord is most knowing of who has strayed from His way, and He is most knowing of who is [rightly] guided.
