Ali 'Imran 3:21

شَهِدَ اللَّهُ أَنَّهُ لَا إِلَـٰهَ إِلَّا هُوَ وَالْمَلَائِكَةُ وَأُولُو الْعِلْمِ قَائِمًا بِالْقِسْطِ ۚ لَا إِلَـٰهَ إِلَّا هُوَ الْعَزِيزُ الْحَكِيمُ

Allah witnesses that there is no deity except Him, and [so do] the angels and those of knowledge - [that He is] maintaining [creation] in justice. There is no deity except Him, the Exalted in Might, the Wise.

إِنَّ الدِّينَ عِندَ اللَّهِ الْإِسْلَامُ ۗ وَمَا اخْتَلَفَ الَّذِينَ أُوتُوا الْكِتَابَ إِلَّا مِن بَعْدِ مَا جَاءَهُمُ الْعِلْمُ بَغْيًا بَيْنَهُمْ ۗ وَمَن يَكْفُرْ بِآيَاتِ اللَّهِ فَإِنَّ اللَّهَ سَرِيعُ الْحِسَابِ

Indeed, the religion in the sight of Allah is Islam. And those who were given the Scripture did not differ except after knowledge had come to them - out of jealous animosity between themselves. And whoever disbelieves in the verses of Allah, then indeed, Allah is swift in [taking] account.

فَإِنْ حَاجُّوكَ فَقُلْ أَسْلَمْتُ وَجْهِيَ لِلَّهِ وَمَنِ اتَّبَعَنِ ۗ وَقُل لِّلَّذِينَ أُوتُوا الْكِتَابَ وَالْأُمِّيِّينَ أَأَسْلَمْتُمْ ۚ فَإِنْ أَسْلَمُوا فَقَدِ اهْتَدَوا ۖ وَّإِن تَوَلَّوْا فَإِنَّمَا عَلَيْكَ الْبَلَاغُ ۗ وَاللَّهُ بَصِيرٌ بِالْعِبَادِ

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.

أُولَـٰئِكَ الَّذِينَ حَبِطَتْ أَعْمَالُهُمْ فِي الدُّنْيَا وَالْآخِرَةِ وَمَا لَهُم مِّن نَّاصِرِينَ

They are the ones whose deeds have become worthless in this world and the Hereafter, and for them there will be no helpers.

أَلَمْ تَرَ إِلَى الَّذِينَ أُوتُوا نَصِيبًا مِّنَ الْكِتَابِ يُدْعَوْنَ إِلَىٰ كِتَابِ اللَّهِ لِيَحْكُمَ بَيْنَهُمْ ثُمَّ يَتَوَلَّىٰ فَرِيقٌ مِّنْهُمْ وَهُم مُّعْرِضُونَ

Do you not consider, [O Muhammad], those who were given a portion of the Scripture? They are invited to the Scripture of Allah that it should arbitrate between them; then a party of them turns away, and they are refusing.

ذَٰلِكَ بِأَنَّهُمْ قَالُوا لَن تَمَسَّنَا النَّارُ إِلَّا أَيَّامًا مَّعْدُودَاتٍ ۖ وَغَرَّهُمْ فِي دِينِهِم مَّا كَانُوا يَفْتَرُونَ

That is because they say, "Never will the Fire touch us except for [a few] numbered days," and [because] they were deluded in their religion by what they were inventing.
