عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ سَأَلْنَا رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَنِ الْجَنِينِ يَكُونُ فِي بَطْنِ النَّاقَةِ أَوِ الْبَقَرَةِ أَوِ الشَّاةِ فَقَالَ كُلُوهُ إِنْ شِئْتُمْ فَإِنَّ ذَكَاتَهُ ذَكَاةُ أُمِّهِ
Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that we asked the Noble Prophet (peace and blessings be upon him) about the offspring found in the womb of a she-camel, cow, or goat, which comes out after the animal is slaughtered. The Prophet (peace and blessings be upon him) said: Slaughtering its mother is (considered) its slaughter as well; if you wish, you may eat it.
