(11) باب دِيَةِ الْجَنِينِ وَوُجُوبِ الدِّيَةِ فِي قَتْلِ الْخَطَإِ وَشِبْهِ الْعَمْدِ عَلَى عَاقِلَةِ الْجَانِي
Miswar b. Makhrama reported that 'Umar b. Khattab consulted people about the diyat of abortion of an unboam child. Mughira b. Shu'ba said:
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.
