'Umar consulted the companions about the case of a woman's abortion (caused by somebody else). Al-Mughira said: The Prophet ﷺ gave the verdict that a male or female slave should be given (as a Diya). Then Muhammad bin Maslama testified that he had witnessed the Prophet ﷺ giving such a verdict.  

الْمُغِيرَةُ قَضَى النَّبِيُّ ﷺ بِالْغُرَّةِ عَبْدٍ أَوْ أَمَةٍ فَقَالَ ائْتِ مَنْ يَشْهَدُ مَعَكَ فَشَهِدَ مُحَمَّدُ بْنُ مَسْلَمَةَ أَنَّهُ شَهِدَ النَّبِيَّ ﷺ قَضَى بِهِ  

I bear witness to the fact that Messenger of Allah 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.  

الْمُغِيرَةُ بْنُ شُعْبَةَ شَهِدْتُ النَّبِيَّ ﷺ قَضَى فِيهِ بِغُرَّةٍ عَبْدٍ أَوْ أَمَةٍ قَالَ فَقَالَ عُمَرُ ائْتِنِي بِمَنْ يَشْهَدُ مَعَكَ قَالَ فَشَهِدَ لَهُ مُحَمَّدُ بْنُ مَسْلَمَةَ  

“Umar bin Khattab consulted the people concerning a woman who had been caused to miscarry. Al-Mughirah bin Shu'bah said: 'I saw the messenger of Allah ﷺ rule that a slave, male or female, be given as blood money (for a fetus).' 'Umar said: 'Bring me someone who will testify alongside you. So he brought Muhammad bin Maslamah to testify along with him.'”  

الْمُغِيرَةُ بْنُ شُعْبَةَ شَهِدْتُ رَسُولَ اللَّهِ ﷺ قَضَى فِيهِ بِغُرَّةٍ عَبْدٍ أَوْ أَمَةٍ فَقَالَ عُمَرُ ائْتِنِي بِمَنْ يَشْهَدُ مَعَكَ فَشَهِدَ مَعَهُ مُحَمَّدُ بْنُ مَسْلَمَةَ  

[Machine] "Lahul Mughiratu qada fihi Rasulullahi salla Allahu 'alayhi wa sallam bil ghurrah faqala lahu 'Umaru in kunta sadiqan fa'ti bi ahadin ya'lamu dhalika fa shahida Muhammad ibnu Muslimah anna Rasulullahi salla Allahu 'alayhi wa sallam qada bihi."

Translation: Mughirah came to the Messenger of Allah ﷺ with a dispute, and the Prophet ﷺ made a decision in his favor. Umar said to him, "If you are truthful, bring someone who knows about this." Muhammad ibn Muslimah testified that the Messenger of Allah ﷺ had indeed made a decision in his favor.  

لَهُ الْمُغِيرَةُ قَضَى فِيهِ رَسُولُ اللهِ ﷺ بِالْغُرَّةِ فَقَالَ لَهُ عُمَرُ إِنْ كُنْتَ صَادِقًا فَأْتِ بِأَحَدٍ يَعْلَمُ ذَلِكَ فَشَهِدَ مُحَمَّدُ بْنُ مَسْلَمَةَ أَنَّ رَسُولَ اللهِ ﷺ قَضَى بِهِ
