Sahih Muslim
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 .
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.
