فَإِنْ Then if حَآجُّوكَ they argue with you فَقُلْ then say أَسْلَمْتُ I have submitted وَجْهِىَ myself لِلَّهِ to Allah وَمَنِ and (those) who ٱتَّبَعَنِ ۗ follow me وَقُل And say لِّلَّذِينَ to those who أُوتُوا۟ were given ٱلْكِتَـٰبَ the Book وَٱلْأُمِّيِّـۧنَ and the unlettered people ءَأَسْلَمْتُمْ ۚ Have you submitted yourselves فَإِنْ Then if أَسْلَمُوا۟ they submit فَقَدِ then surely ٱهْتَدَوا۟ ۖ they are guided وَّإِن But if تَوَلَّوْا۟ they turn back فَإِنَّمَا then only عَلَيْكَ on you ٱلْبَلَـٰغُ ۗ (is) to [the] convey وَٱللَّهُ And Allah بَصِيرٌۢ (is) All-Seer بِٱلْعِبَادِ of [His] slaves ٢٠
So if they argue with you, say, "I have submitted myself to Allāh [in Islām], 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 Islām], they are rightly guided; but if they turn away - then upon you is only the [duty of] notification. And Allāh is Seeing of [His] servants.
