Musnad Ahmad 826
Hujayyah bin ‘Adiyy, a man from Kindah, said:
I heard a man ask `Ali (رضي الله عنه): I bought this cow to offer it as a sacrifice. He said:[It may be offered on behalf of seven people. He said: [What if something is wrong with] the horn? He said: It does not matter. He said: [What if it is] lame? He said: If it can reach the place of sacrifice, then sacrifice it. Then he said: The Messenger of Allah (ﷺ) commanded us to check the eyes and ears.
حَدَّثَنَا عَفَّانُ، حَدَّثَنَا شُعْبَةُ، قَالَ سَلَمَةُ بْنُ كُهَيْلٍ أَنْبَأَنِي قَالَ سَمِعْتُ حُجَيَّةَ بْنَ عَدِيٍّ، رَجُلًا مِنْ كِنْدَةَ قَالَ سَمِعْتُ رَجُلًا، سَأَلَ عَلِيًّا رَضِيَ اللَّهُ عَنْهُ قَالَ إِنِّي اشْتَرَيْتُ هَذِهِ الْبَقَرَةَ لِلْأَضْحَى قَالَ عَنْ سَبْعَةٍ قَالَ الْقَرْنُ قَالَ لَا يَضُرُّكَ قَالَ الْعَرَجُ قَالَ إِذَا بَلَغَتْ الْمَنْسَكَ فَانْحَرْ ثُمَّ قَالَ أَمَرَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ نَسْتَشْرِفَ الْعَيْنَ وَالْأُذُنَ‏.‏
