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
fa-in ḥājjūka faqul aslamtu wajhiya lillahi wamani ittabaʿani waqul lilladhīna ūtū l-kitāba wal-umiyīna a-aslamtum fa-in aslamū faqadi ih'tadaw wa-in tawallaw fa-innamā ʿalayka l-balāghu wal-lahu baṣīrun bil-ʿibādi
if they argue with you [Prophet], say, ‘I have devoted myself to God alone and so have my followers.’ Ask those who were given the Scripture, as well as those without one, ‘Do you too devote yourselves to Him alone?’ If they do, they will be guided, but if they turn away, your only duty is to convey the message. God is aware of His servants.
So if they dispute with you (Muhammad صلى الله عليه وسلم) say: "I have submitted myself to Allâh (in Islâm), 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 Allâh in Islâm)?" If they do, they are rightly guided; but if they turn away, your duty is only to convey the Message; and Allâh is All-Seer of (His) slaves.
