فَاِنۡ حَآجُّوۡكَ فَقُلۡ اَسۡلَمۡتُ وَجۡهِىَ لِلّٰهِ وَمَنِ اتَّبَعَنِؕ وَقُل لِّلَّذِيۡنَ اُوۡتُوا الۡكِتٰبَ وَالۡاُمِّيّٖنَ ءَاَسۡلَمۡتُمۡؕ فَاِنۡ اَسۡلَمُوۡا فَقَدِ اهۡتَدَوْا ۚ وَاِنۡ تَوَلَّوۡا فَاِنَّمَا عَلَيۡكَ الۡبَلٰغُ ؕ وَاللّٰهُ بَصِيۡرٌۢ بِالۡعِبَادِ

So if they argue with you, say, "I have submitted myself to Allāh in Islām, and so have those who follow me." And say to those who were given the Scripture and to the unlearned, "Have you submitted yourselves?" And if they submit in Islām, they are rightly guided; but if they turn away - then upon you is only the duty of notification. And Allāh is Seeing of His servants.
