Arabic hadith text
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، عَنْ هِشَامٍ، عَنْ أَبِيهِ، أَنْ عُمَرَ، نَشَدَ النَّاسَ مَنْ سَمِعَ النَّبِيَّ صلى الله عليه وسلمقَضَى فِي السِّقْطِ وَقَالَ الْمُغِيرَةُ أَنَا سَمِعْتُهُ قَضَى فِيهِ بِغُرَّةٍ عَبْدٍ أَوْ أَمَةٍ‏.‏ قَالَ ائْتِ مَنْ يَشْهَدُ مَعَكَ عَلَى هَذَا فَقَالَ مُحَمَّدُ بْنُ مَسْلَمَةَ أَنَا أَشْهَدُ عَلَى النَّبِيِّ صلى الله عليه وسلم بِمِثْلِ هَذَا‏.‏
Translation
Narrated Hisham's father

'Umar asked the people, "Who heard the Prophet (ﷺ) giving his verdict regarding abortions?" Al-Mughira said, "I heard him judging that a male or female slave should be given (as a Diya)." 'Umar said, "Present a witness to testify your statement." Muhammad bin Maslama said, "I testify that the Prophet (ﷺ) gave such a judgment."
