They swear by Allah that they did not say ˹anything against the Prophet˺ while they had said the word of disbelief and disbelieved after their ˹pretense of˺ Islam and planned that which they were not to attain. And they were not resentful except ˹for the fact˺ that Allah and His Messenger had enriched them of His bounty. So if they repent, it is better for them; but if they turn away, Allah will punish them with a painful punishment in this world and the Hereafter. And there will not be for them on earth any protector or helper.  

يَحْلِفُونَ بِاللَّهِ مَا قَالُوا وَلَقَدْ قَالُوا كَلِمَةَ الْكُفْرِ وَكَفَرُوا بَعْدَ إِسْلَامِهِمْ وَهَمُّوا بِمَا لَمْ يَنَالُوا ۚ وَمَا نَقَمُوا إِلَّا أَنْ أَغْنَاهُمُ اللَّهُ وَرَسُولُهُ مِنْ فَضْلِهِ ۚ فَإِنْ يَتُوبُوا يَكُ خَيْرًا لَهُمْ ۖ وَإِنْ يَتَوَلَّوْا يُعَذِّبْهُمُ اللَّهُ عَذَابًا أَلِيمًا فِي الدُّنْيَا وَالْآخِرَةِ ۚ وَمَا لَهُمْ فِي الْأَرْضِ مِنْ وَلِيٍّ وَلَا نَصِيرٍ  

"A man killed another man during the time of the Messenger of Allah, and the Prophet set the Diyah at twelve thousand. And he mentioned His saying: And they could not find any cause to do so except that Allah and His Messenger had enriched them of His Bounty. concerning them taking the Dyah." (Hasan) This is the wording of Abu Dawud.  

قَتَلَ رَجُلٌ رَجُلاً عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فَجَعَلَ النَّبِيُّ ﷺ دِيَتَهُ اثْنَىْ عَشَرَ أَلْفًا وَذَكَرَ قَوْلَهُ إِلاَّ أَنْ أَغْنَاهُمُ اللَّهُ وَرَسُولُهُ مِنْ فَضْلِهِ فِي أَخْذِهِمُ الدِّيَةَ وَاللَّفْظُ لأَبِي دَاوُدَ
