“The Companions of the Messenger of Allah ﷺ said: ‘O Messenger of Allah, what are these sacrifices?’ He said: ‘The Sunnah of your father Ibrahim.’ They said: ‘What is there for us in them, O Messenger of Allah?’ He said: ‘For every hair, one merit.’ They said: ‘What about wool, O Messenger of Allah?’ He said: ‘For every hair of wool, one merit.’” (Using translation from Ibn Mājah 3127)
قَالُوا يَا رَسُولَ اللهِ مَا هَذِهِ الْأَضَاحِيُّ؟ قَالَ «سُنَّةُ أَبِيكُمْ إِبْرَاهِيمَ» قَالُوا فَمَا لَنَا فِيهَا مِنَ الْأَجْرِ؟ قَالَ «بِكُلِّ شَعْرَةٍ حَسَنَةٌ» قَالُوا فَالصُّوفُ قَالَ «بِكُلِّ شَعْرَةٍ حَسَنَةٌ»
