[Machine] The Messenger of Allah ﷺ dislikes seven things from sheep: blood, bile, penis, two testicles, intestines, bladder, and gallbladder. It was mentioned that he ﷺ preferred the anterior part of the sheep, and this narration is disconnected (i.e. weak). Omar bin Musa bin Wajih narrated it, and he is weak, from Wasil bin Abi Jameel from Mujahid from Ibn Abbas, that the Prophet ﷺ disliked eating the seven mentioned things from a sheep. Abu Saad Al-Malini narrated the Hadith to us, Abu Ahmad bin Adi narrated it to us, Wahkar bin Al-Husain Al-Raqqi narrated to us, Ayoub Al-Wazzan narrated to us, and Omar bin Musa mentioned it, but it is a Mawsool (connected) narration and its connection is not valid. Abu Sulaiman Al-Khattabi said regarding what I have heard from him: blood is prohibited unanimously, and the mentioned things are generally disliked but not prohibited.  

رَسُولُ اللهِ ﷺ يَكْرَهُ مِنَ الشَّاةِ سَبْعًا الدَّمَ وَالْمَرَارَ وَالذَّكَرَ وَالْأُنْثَيَيْنِ وَالْحَيَا وَالْغُدَّةَ وَالْمَثَانَةَ قَالَ وَكَانَ أَعْجَبَ الشَّاةِ إِلَيْهِ ﷺ مُقَدِّمُهَا هَذَا مُنْقَطِعٌ 19701 وَرَوَاهُ عُمَرُ بْنُ مُوسَى بْنِ وَجِيهٍ وَهُوَ ضَعِيفٌ عَنْ وَاصِلِ بْنِ أَبِي جَمِيلٍ عَنْ مُجَاهِدٍ عَنِ ابْنِ عَبَّاسٍ ؓ أَنَّ النَّبِيَّ ﷺ كَانَ يَكْرَهُ أَكْلَ سَبْعٍ مِنَ الشَّاةِ فَذَكَرَ الْحَدِيثَ أَخْبَرَنَاهُ أَبُو سَعْدٍ الْمَالِينِيُّ أنبأ أَبُو أَحْمَدَ بْنُ عَدِيٍّ ثنا وَقَّارُ بْنُ الْحُسَيْنِ الرَّقِّيُّ ثنا أَيُّوبُ الْوَزَّانُ ثنا فِهْرُ بْنُ بَشِيرٍ ثنا عُمَرُ بْنُ مُوسَى فَذَكَرَهُ مَوْصُولًا وَلَا يَصِحُّ وَصْلُهُ قَالَ أَبُو سُلَيْمَانَ الْخَطَّابِيُّ فِيمَا بَلَغَنِي عَنْهُ الدَّمُ حَرَامٌ بِالْإجْمَاعِ وَعَامَّةُ الْمَذْكُورَاتِ مَعَهُ مَكْرُوهَةٌ غَيْرُ مُحَرَّمَةٍ
