Aal-i-Imraan 20

فَإِنْ حَآجُّوكَ فَقُلْ أَسْلَمْتُ وَجْهِىَ لِلَّهِ وَمَنِ ٱتَّبَعَنِ وَقُل لِّلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ وَٱلْأُمِّيِّۦنَ ءَأَسْلَمْتُمْ فَإِنْ أَسْلَمُوا۟ فَقَدِ ٱهْتَدَوا۟ وَّإِن تَوَلَّوْا۟ فَإِنَّمَا عَلَيْكَ ٱلْبَلَٰغُ وَٱللَّهُ بَصِيرٌۢ بِٱلْعِبَادِ ﴿٢٠﴾

Fain hajjooka faqul aslamtu wajhiya lillahi wamani ittabaAAani waqul lillatheena ootoo alkitaba waalommiyyeena aaslamtum fain aslamoo faqadi ihtadaw wain tawallaw fainnama AAalayka albalaghu waAllahu baseerun bialAAibadi

So if they dispute with you (Muhammad SAW) say: "I have submitted myself to Allah (in Islam), and (so have) those who follow me." And say to those who were given the Scripture (Jews and Christians) and to those who are illiterates (Arab pagans): "Do you (also) submit yourselves (to Allah in Islam)?" If they do, they are rightly guided; but if they turn away, your duty is only to convey the Message; and Allah is All-Seer of (His) slaves. The Noble Quran
