وَعَنْ زَيْدِ بْنِ أَرْقَمَ قَالَ: قَالَ أَصْحَابُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: يَا رَسُولَ اللَّهِ مَا هَذِهِ الْأَضَاحِيُّ؟ قَالَ: «سُنَّةُ أبيكم إِبْرَاهِيم عَلَيْهِ السَّلَام» قَالُوا: فَمَا لَنَا فِيهَا يَا رَسُولَ اللَّهِ؟ قَالَ: «بِكُلِّ شَعْرَةٍ حَسَنَةٌ» . قَالُوا: فَالصُّوفُ يَا رَسُولَ اللَّهِ؟ قَالَ: «بِكُلِّ شَعْرَةٍ مِنَ الصُّوفِ حَسَنَة» رَوَاهُ أَحْمد وَابْن مَاجَه
English Translation
Zaid b. Arqam said the companions of God’s Messenger asked him the significance of these sacrifices and he replied, “It is a custom which has come down from your father Abraham." They asked what reward they would receive for them and he replied, “For every hair you will receive a blessing." They asked about wool, and he replied, “For every strand of wool you will receive a blessing." Ahmad and Ibn Majah transmitted it.
