Surah Ali 'Imran
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 fa qul aslamtu wajhiya lillāhi wa manittaba‘an(i), wa qul lil-lażīna ūtul-kitāba wal-ummiyyīna a'aslamtum, fa'in aslamū faqadihtadau, wa in tawallau fa'innamā ‘alaikal-balāg(u), wallāhu baṣīrum bil-‘ibād(i).
So if they argue with you, 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 and [to] the unlearned, "Have you submitted yourselves?" And if they submit [in Islam], they are rightly guided; but if they turn away - then upon you is only the [duty of] notification. And Allah is Seeing of [His] servants.
