"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." (Using translation from Nasāʾī 4383)  

كُنَّا فِي سَفَرٍ فَحَضَرَ الْأَضْحَى فَجَعَلَ الرَّجُلُ يَشْتَرِي مِنَّا الْمُسِنَّةَ بِالْجَذَعَيْنِ وَالثَّلَاثَةِ فَقَالَ لَنَا رَجُلٌ مِنْ مُزَيْنَةَ كُنَّا مَعَ رَسُولِ اللهِ ﷺ فِي سَفَرٍ فَحَضَرَ هَذَا الْيَوْمُ فَجَعَلَ الرَّجُلُ يَطْلُبُ الْمُسِنَّةَ بِالْجَذَعَتَيْنِ وَالثَّلَاثَةِ فَقَالَ رَسُولُ اللهِ ﷺ «إِنَّ الْجَذَعَ يُوفِي مِمَّا يُوفِي مِنْهُ الثَّنِيُّ»
