Sunan Ibn Majah Book 26, Hadith 3140

حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَنْبَأَنَا الثَّوْرِيُّ، عَنْ عَاصِمِ بْنِ كُلَيْبٍ، عَنْ أَبِيهِ، قَالَ كُنَّا مَعَ رَجُلٍ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ يُقَالُ لَهُ مُجَاشِعٌ مِنْ بَنِي سُلَيْمٍ فَعَزَّتِ الْغَنَمُ فَأَمَرَ مُنَادِيًا فَنَادَى أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ كَانَ يَقُولُ ‏ "‏ إِنَّ الْجَذَعَ يُوفِي مِمَّا تُوفِي مِنْهُ الثَّنِيَّةُ ‏"‏ ‏.‏

It was narrated from ‘Asim bin Kulaib that his father said:“We were with a man from among the Companions of the Messenger of Allah (ﷺ) who was called Mujashi’, from Banu Sulaim, and sheep became scarce. He ordered a caller to call out that the Messenger of Allah (ﷺ) used to say: ‘A Jadha’a suffices for whatever a two-year-old sheep suffices.’”
