I saw ‘Ali ؓ sacrificing two rams and I said to him: “What is this?” He said: “The Messenger of Allah ﷺ told me to offer a sacrifice on his behalf”.  

أحمد:١٢٨٦ – حَدَّثَنَا عَبْدُ اللهِ حَدَّثَنِي عُثْمَانُ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا شَرِيكٌ عَنْ أَبِي الْحَسْنَاءِ عَنِ الْحَكَمِ عَنْ حَنَشٍ قَالَ

رَأَيْتُ عَلِيًّا يُضَحِّي بِكَبْشَيْنِ فَقُلْتُ لَهُ مَا هَذَا؟ فَقَالَ أَوْصَانِي رَسُولُ اللهِ ﷺ أَنْ أُضَحِّيَ عَنْهُ
