[Machine] Allah ﷺ said: "No action performed by the son of Adam on the Day of Sacrifice is dearer to Allah than shedding blood. It will come on the Day of Resurrection with its horns, hooves, and feathers, and indeed the blood falls in a place before it falls on the ground. So, purify yourselves with it." Al-Bukhari reported from Abu 'Isa that this is a Mursal Hadith, which Abu al-Muthanna did not hear from Hisham ibn 'Urwah. Sheikh Ahmad said.  

اللهِ ﷺ قَالَ مَا عَمِلَ آدَمِيٌّ مِنْ عَمَلٍ يَوْمَ النَّحْرِ أَحَبَّ إِلَى اللهِ مِنْ إِهْرَاقِ دَمٍ وَإِنَّهُ لَيَأْتِي يَوْمَ الْقِيَامَةِ فِي قَرْنِهِ بِقُرُونِهَا وَأَشْعَارِهَا وَأَظْلَافِهَا وَإِنَّ الدَّمَ لَيَقَعُ مِنَ اللهِ بِمَكَانٍ قَبْلَ أَنْ يَقَعَ فِي الْأَرْضِ فَطِيبُوا بِهَا نَفْسًا قَالَ الْبُخَارِيُّ فِيمَا حَكَى أَبُو عِيسَى عَنْهُ هُوَ حَدِيثٌ مُرْسَلٌ لَمْ يَسْمَعْ أَبُو الْمُثَنَّى مِنْ هِشَامِ بْنِ عُرْوَةَ قَالَ الشَّيْخُ أَحْمَدُ
