Verse 20

فَإِنْ حَآجُّوكَ فَقُلْ أَسْلَمْتُ وَجْهِىَ لِلَّهِ وَمَنِ ٱتَّبَعَنِ وَقُل لِّلَّذِينَ أُوتُوا۟ ٱلْكِتَـٰبَ وَٱلْأُمِّيِّـۧنَ ءَأَسْلَمْتُمْ فَإِنْ أَسْلَمُوا۟ فَقَدِ ٱهْتَدَوا۟ وَّإِن تَوَلَّوْا۟ فَإِنَّمَا عَلَيْكَ ٱلْبَلَـٰغُ وَٱللَّهُ بَصِيرٌۢ بِٱلْعِبَادِ

Therefore, if they argue with you, then say, I am at peace with God and so do those who follow me. Moreover, say to those who received the scripture as well as the laymen, will you attain peace? Then if they attain peace, they immediately are guided, and if they turn away, then indeed your only responsibility is to deliver. And God is All Seer of the servants.
