النحل — An-Nahl Ayat 125
اُدْعُ اِلٰى سَبِيْلِ رَبِّكَ بِالْحِكْمَةِ وَالْمَوْعِظَةِ الْحَسَنَةِ وَجَادِلْهُمْ بِالَّتِيْ هِيَ اَحْسَنُۗ اِنَّ رَبَّكَ هُوَ اَعْلَمُ بِمَنْ ضَلَّ عَنْ سَبِيْلِهٖ وَهُوَ اَعْلَمُ بِالْمُهْتَدِيْنَ
Ud‘u ilā sabīli rabbika bil-ḥikmati wal-mau‘iẓatil-ḥasanati wa jādilhum bil-latī hiya aḥsan(u), inna rabbaka huwa a‘lamu biman ḍalla ‘an sabīlihī wa huwa a‘lamu bil-muhtadīn(a).
"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."
