Surah Al-Imran, 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 ﴿٢٠﴾

3:20 Then if they argue with you, say, “I have submitted myself to Allah, and so have those who follow me.” And say to those who were given the Scripture and to the illiterate, “Have you submitted yourselves?” If they do, then they are rightly guided, but if they turn away, your duty is only to convey the message. And Allah is All-Seeing of His slaves
