عَنْ عَاصِمِ بْنِ كُلَيْبٍ عَنْ أَبِيهِ عَنْ رَجُلٍ مِنْ مُزَيْنَةَ أَوْ جُهَيْنَةَ قَالَ كَانَ أَصْحَابُ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا كَانَ قَبْلَ الْأَضْحَى بِيَوْمٍ أَوْ بِيَوْمَيْنِ أَعْطَوْا جَذَعَيْنِ وَأَخَذُوا ثَنِيًّا فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِنَّ الْجَذَعَةَ تُجْزِئُ مِمَّا تُجْزِئُ مِنْهُ الثَّنِيَّةُ
A man from the tribe of Muzaynah or Juhaynah narrates that the companions of the Holy Prophet (peace and blessings be upon him) used to give two young animals (Jadha') each, a day or two before Eid al-Adha, and in exchange would take one animal with two permanent teeth (Donda). The Messenger of Allah (peace and blessings be upon him) said: Indeed, a young animal (Jadha') suffices for what an animal with two permanent teeth (Donda) suffices.
