حَدَّثَنَا مُحَمَّدُ بْنُ مَسْعُودٍ الْمِصِّيصِيُّ، حَدَّثَنَا أَبُو عَاصِمٍ، عَنِ ابْنِ جُرَيْجٍ، قَالَ أَخْبَرَنِي عَمْرُو بْنُ دِينَارٍ، أَنَّهُ سَمِعَ طَاوُسًا، عَنِ ابْنِ عَبَّاسٍ، عَنْ عُمَرَ، أَنَّهُ سَأَلَ عَنْ قَضِيَّةِ النَّبِيِّ، صلى الله عليه وسلم فِي ذَلِكَ فَقَامَ إِلَيْهِ حَمَلُ بْنُ مَالِكِ بْنِ النَّابِغَةِ فَقَالَ كُنْتُ بَيْنَ امْرَأَتَيْنِ فَضَرَبَتْ إِحْدَاهُمَا الأُخْرَى بِمِسْطَحٍ فَقَتَلَتْهَا وَجَنِينَهَا فَقَضَى رَسُولُ اللَّهِ صلى الله عليه وسلم فِي جَنِينِهَا بِغُرَّةٍ وَأَنْ تُقْتَلَ ‏.‏ قَالَ أَبُو دَاوُدَ قَالَ النَّضْرُ بْنُ شُمَيْلٍ الْمِسْطَحُ هُوَ الصَّوْبَجُ ‏.‏ قَالَ أَبُو دَاوُدَ وَقَالَ أَبُو عُبَيْدٍ الْمِسْطَحُ عُودٌ مِنْ أَعْوَادِ الْخِبَاءِ ‏.‏

Narrated Ibn 'Abbas: 'Umar asked about the decision of the Prophet (PBUH) about that (i.e. abortion). Haml b. Malik b. al-Nabhigah got up and said: I was between two women. One of them struck another with a rolling-pin killing both her and what was in her womb. So the Messenger of Allah (PBUH) gave judgement that the bloodwit for the unborn child should be a male or a female slave of the best quality and the she should be killed. Abu Dawud said: Al-Nadr b. Shumail said: Mistah means a rolling-pin. Abu Dawud said: Abu 'Ubaid said: Mistah means a pole from the tent-poles. Translation Not Available
