عَنْ حَنَشٍ قَالَ رَأَيْتُ عَلِيًّا رَضِيَ اللَّهُ عَنْهُ يُضَحِّي بِكَبْشَيْنِ فَقُلْتُ لَهُ مَا هَذَا فَقَالَ أَوْصَانِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنْ أُضَحِّيَ عَنْهُ
It is narrated from Hanish, he says: I saw Sayyiduna Ali (may Allah be pleased with him) sacrificing two rams. I asked him: What is this? He said: The Messenger of Allah (peace and blessings be upon him) advised me to offer a sacrifice on his behalf.
