عن زيد بن أرقم رضي الله عنه قال قال أصحاب رسول الله صلى الله عليه وسلم يا رسول الله ما هذه الأضاحي قال سنة أبيكم إبراهيم عليه السلام قالوا فما لنا فيها يا رسول الله قال بكل شعرة حسنة قالوا فالصوف يا رسول الله قال بكل شعرة من الصوف حسنة (سنن ابن ماجه، الرقم: 3127)
Hazrat Zaid bin Arqam (radhiyallahu anhu) reports that the Sahaabah (radhiyallahu anhum) once enquired from Rasulullah (sallallahu alaihi wasallam), “O Rasulullah (sallallahu alaihi wasallam), what is the significance of this action of qurbaani?” Rasulullah (sallallahu alaihi wasallam) replied, “It is the practice of your forefather, Ebrahim (alaihis salaam).” The Sahaabah (radhiyallahu anhum) then asked, “O Rasulullah (sallallahu alaihi wasallam)! What reward will we receive through carrying it out?” Rasulullah (sallallahu alaihi wasallam) replied, “For every strand of hair (on the back of the animal), you will receive a reward.” The Sahaabah (radhiyallahu anhum) then asked, “O Rasulullah (sallallahu alaihi wasallam), what about wool?” Rasulullah (sallallahu alaihi wasallam) replied, “For every fibre of wool (on the back of the animal), you will receive a reward.”
