It was narrated from 'Asim bin Kulaib that his father said: "We were on a journey and the day of Al-adha came, so we started to by sheep, a Musinnah for two or three Jadh'ahs. A man from Muzainah said to us: 'We were with the Messenger of Allah on a journey when this came, and we stated to look for sheep, (offering to buy) aMusinnah for two or three Jadh'ahs. Then the Messenger of Allah said: "A Jadh'ah is sufficient for that for which a Thani is sufficient."

أَخْبَرَنَا هَنَّادُ بْنُ السَّرِيِّ، فِي حَدِيثِهِ عَنْ أَبِي الأَحْوَصِ، عَنِ عَاصِمِ بْنِ كُلَيْبٍ، عَنْ أَبِيهِ، قَالَ كُنَّا فِي سَفَرٍ فَحَضَرَ الأَضْحَى فَجَعَلَ الرَّجُلُ مِنَّا يَشْتَرِي الْمُسِنَّةَ بِالْجَذَعَتَيْنِ وَالثَّلاَثَةِ فَقَالَ لَنَا رَجُلٌ مِنْ مُزَيْنَةَ كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي سَفَرٍ فَحَضَرَ هَذَا الْيَوْمُ فَجَعَلَ الرَّجُلُ يَطْلُبُ الْمُسِنَّةَ بِالْجَذَعَتَيْنِ وَالثَّلاَثَةِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ إِنَّ الْجَذَعَ يُوفِي مِمَّا يُوفِي مِنْهُ الثَّنِيُّ ‏" ‏ ‏.‏
