Arabic hadith text
حَدَّثَنَا الْعَبَّاسُ بْنُ جَعْفَرٍ، حَدَّثَنَا مُحَمَّدُ بْنُ سِنَانٍ، حَدَّثَنَا مُحَمَّدُ بْنُ مُسْلِمٍ، عَنْ عَمْرِو بْنِ دِينَارٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلمجَعَلَ الدِّيَةَ اثْنَىْ عَشَرَ أَلْفًا قَالَ ذَلِكَ قَوْلُهُ ‏‏{وَمَا نَقَمُوا إِلاَّ أَنْ أَغْنَاهُمُ اللَّهُ وَرَسُولُهُ مِنْ فَضْلِهِ}‏ قَالَ بِأَخْذِهِمُ الدِّيَةَ ‏.‏
Translation
It was narrated from 'Ikrimah, from Ibn 'Abbas, that

the Prophet (ﷺ) set the blood money at twelve thousand (Dirham). He said: “This is what Allah says: 'And they could not find any cause to do so except that Allah and his Messenger (ﷺ) had enriched them of His bounty.'” He said: “By their taking the blood money.”
