3:23
أَلَمْ تَرَ إِلَى ٱلَّذِينَ أُوتُوا۟ نَصِيبًا مِّنَ ٱلْكِتَـٰبِ يُدْعَوْنَ إِلَىٰ كِتَـٰبِ ٱللَّهِ 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.

إِنَّ ٱلَّذِينَ يَكْفُرُونَ بِـَٔايَـٰتِ ٱللَّهِ وَيَقْتُلُونَ ٱلنَّبِيِّـۧنَ بِغَيْرِ حَقٍّ وَيَقْتُلُونَ ٱلَّذِينَ يَأْمُرُونَ بِٱلْقِسْطِ مِنَ ٱلنَّاسِ فَبَشِّرْهُم بِعَذَابٍ أَلِيمٍ
Those who disbelieve in the signs of Allah and kill the prophets without right and kill those who order justice from among the people - give them tidings of a painful punishment.
أُو۟لَـٰٓئِكَ ٱلَّذِينَ حَبِطَتْ أَعْمَـٰلُهُمْ فِى ٱلدُّنْيَا وَٱلْـَٔاخِرَةِ وَمَا لَهُم مِّن نَّـٰصِرِينَ
They are the ones whose deeds have become worthless in this world and the Hereafter, and for them there will be no helpers.
ذَٰلِكَ بِأَنَّهُمْ قَالُوا۟ لَن تَمَسَّنَا ٱلنَّارُ إِلَّآ أَيَّامًا مَّعْدُودَٰتٍ ۖ وَغَرَّهُمْ فِى دِينِهِم مَّا كَانُوا۟ 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.
فَكَيْفَ إِذَا جَمَعْنَـٰهُمْ لِيَوْمٍ لَّا رَيْبَ فِيهِ وَوُفِّيَتْ كُلُّ نَفْسٍ مَّا كَسَبَتْ وَهُمْ لَا يُظْلَمُونَ
So how will it be when We assemble them for a Day about which there is no doubt? And each soul will be compensated [in full for] what it earned, and they will not be wronged.
