ادعُ إِلىٰ سَبيلِ رَبِّكَ بِالحِكمَةِ وَالمَوعِظَةِ الحَسَنَةِ ۖ وَجادِلهُم بِالَّتي هِيَ أَحسَنُ ۚ إِنَّ رَبَّكَ هُوَ أَعلَمُ بِمَن ضَلَّ عَن سَبيلِهِ ۖ وَهُوَ أَعلَمُ بِالمُهتَدينَ

Invite to the path of your Lord through wisdom and kind advice, and engage in discussions in the most courteous manner. Your Lord knows best who strays from His path, and He knows best those who are rightly guided.
