Sahih Muslim 1683
Sahih Muslim · Book 28: The Book of Oaths, Muharibin , Qasas (Retaliation), and Diyat (Blood Money) · The Diyah for a fetus; and the Diyah for accidental killing and the ambiguous killing must be paid by the shahiqilah of the killer
Miswar b. Makhrama reported that 'Umar b. Khattab consulted people about the diyat of abortion of an unboam child. Mughira b. Shu'ba said:
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، وَأَبُو كُرَيْبٍ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ - وَاللَّفْظُ لأَبِي بَكْرٍ - قَالَ إِسْحَاقُ أَخْبَرَنَا وَقَالَ الآخَرَانِ، حَدَّثَنَا وَكِيعٌ ، عَنْ هِشَامِ بْنِ عُرْوَةَ ، عَنْ أَبِيهِ ، عَنِ الْمِسْوَرِ بْنِ مَخْرَمَةَ ، قَالَ اسْتَشَارَ عُمَرُ بْنُ الْخَطَّابِ النَّاسَ فِي إِمْلاَصِ الْمَرْأَةِ فَقَالَ الْمُغِيرَةُ بْنُ شُعْبَةَ شَهِدْتُ النَّبِيَّ صلى الله عليه وسلم قَضَى فِيهِ بِغُرَّةٍ عَبْدٍ أَوْ أَمَةٍ . قَالَ فَقَالَ عُمَرُ ائْتِنِي بِمَنْ يَشْهَدُ مَعَكَ قَالَ فَشَهِدَ لَهُ مُحَمَّدُ بْنُ مَسْلَمَةَ .
I bear witness to the fact that Allah's Messenger (ﷺ) gave judgment about it that a good quality of slave or female slave should be given for it. Thereupon 'Umar said: Bring one who may bear witness to you. Then Muhammad b. Maslama bore witness to him.
