Sunan Ibn Majah, Volume 4, Book 26, Hadith 3126 (DarusSalam) ⓘ
It was narrated from ’Aishah that the Prophet said: “The son of Adam does not do any deed on the Day of Sacrifice that is dearer to Allah than shedding blood. It will come on the Day of Resurrection with its horns and cloven hoofs and hair. Its blood is accepted by Allah before it reaches the ground. So be content when you do it.”
حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ إِبْرَاهِيمَ الدِّمَشْقِيُّ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نَافِعٍ، حَدَّثَنِي أَبُو الْمُثَنَّى، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ قَالَ " مَا عَمِلَ ابْنُ آدَمَ يَوْمَ النَّحْرِ عَمَلاً أَحَبَّ إِلَى اللَّهِ عَزَّ وَجَلَّ مِنْ هِرَاقَةِ دَمٍ وَإِنَّهُ لَيَأْتِي يَوْمَ الْقِيَامَةِ بِقُرُونِهَا وَأَظْلاَفِهَا وَأَشْعَارِهَا وَإِنَّ الدَّمَ لَيَقَعُ مِنَ اللَّهِ عَزَّ وَجَلَّ بِمَكَانٍ قَبْلَ أَنْ يَقَعَ عَلَى الأَرْضِ فَطِيبُوا بِهَا نَفْسًا " .
