عَنْ سَلَمَةَ بْنِ كُهَيْلٍ عَنْ حُجَيَّةَ قَالَ سَأَلَ رَجُلٌ عَلِيًّا رَضِيَ اللَّهُ عَنْهُ عَنِ الْبَقَرَةِ فَقَالَ عَنْ سَبْعَةٍ فَقَالَ مَكْسُورَةُ الْقَرْنِ فَقَالَ لَا يَضُرُّكَ قَالَ الْعَرْجَاءُ قَالَ إِذَا بَلَغَتِ الْمَنْسَكَ فَاذْبَحْ أَمَرَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنْ نَسْتَثْرِفَ الْعَيْنَ وَالْأُذُنَ
Hujiyyah narrates that a man asked Sayyiduna Ali (may Allah be pleased with him) about a cow. He said: On behalf of seven people. He asked: If its horn is broken? He said: This thing will not harm you. He asked: If the animal is lame? He said: When it reaches the place of sacrifice, then slaughter it. The Messenger of Allah (peace and blessings be upon him) commanded us to carefully observe the eyes and ears.
