Sunan Abi Dawud, Hadith 2821 ⓘ
Narrated AbuSa'id al-Khudri: I asked the Messenger of Allah about the embryo. He replied: Eat it if you wish. Musaddad's version says: we said: Messenger of Allah, we slaughter a she-camel, a cow and a sheep, and we find an embryo in its womb. Shall we throw it away or eat it? He replied: Eat it if you wish for the slaughter of its mother serves its slaughter.
حَدَّثَنَا الْقَعْنَبِيُّ، حَدَّثَنَا ابْنُ الْمُبَارَكِ، ح وَحَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا هُشَيْمٌ، عَنْ مُجَالِدٍ، عَنْ أَبِي الْوَدَّاكِ، عَنْ أَبِي سَعِيدٍ، قَالَ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنِ الْجَنِينِ فَقَالَ " كُلُوهُ إِنْ شِئْتُمْ " . وَقَالَ مُسَدَّدٌ قُلْنَا يَا رَسُولَ اللَّهِ نَنْحَرُ النَّاقَةَ وَنَذْبَحُ الْبَقَرَةَ وَالشَّاةَ فَنَجِدُ فِي بَطْنِهَا الْجَنِينَ أَنُلْقِيهِ أَمْ نَأْكُلُهُ قَالَ " كُلُوهُ إِنْ شِئْتُمْ فَإِنَّ ذَكَاتَهُ ذَكَاةُ أُمِّهِ " .
