[Machine] Abu al-Walid al-Tayalisi and Abu Umar al-Hawdi narrated, they said, Shu'ba narrated from Salamah ibn Kuhayl who said, I heard Hujayy ibn 'Adi say, I heard Ali being asked about the cow and he said, regarding four. He was then asked about the cow with a broken horn and he said, it does not harm you. He was then asked about the lame cow and he said, when it reaches the place of sacrifice. He also said, "The Messenger of Allah ﷺ commanded us to perform istishraf of the eye and ear." All these chains of narration are authentic, and they did not rely on the narration of Ibn 'Adi, who was one of the prominent companions of Amir al-Mu'minin Ali.  

ثَنَا أَبُو الْوَلِيدِ الطَّيَالِسِيُّ وَأَبُو عُمَرَ الْحَوْضِيُّ قَالَا ثَنَا شُعْبَةُ عَنْ سَلَمَةَ بْنِ كُهَيْلٍ قَالَ سَمِعْتُ حُجَيَّةَ بْنَ عَدِيٍّ يَقُولُ سَمِعْتُ عَلِيًّا وَسَأَلَهُ رَجُلٌ عَنِ الْبَقَرَةِ فَقَالَ عَنْ سَبْعَةٍ قَالَ وَسَأَلَهُ عَنْ مَكْسُورَةِ الْقَرْنِ؟ قَالَ لَا تَضُرُّكَ قَالَ وَسَأَلَهُ عَنِ الْعَرْجِ؟ قَالَ إِذَا بَلَغَ الْمَنْسَكَ وَقَالَ «أَمَرَنَا رَسُولُ اللَّهِ ﷺ أَنْ نَسْتَشْرِفَ الْعَيْنَ وَالْأُذُنَ» هَذِهِ الْأَسَانِيدُ كُلُّهَا صَحِيحَةٌ وَلَمْ يَحْتَجَّا بِحُجَّيَةَ ابْنِ عَدِيٍّ وَهُوَ مِنْ كِبَارِ أَصْحَابِ أَمِيرِ الْمُؤْمِنِينَ عَلِيٍّ صحيح
