Narrated 'Asim b. Kulaib:

On the authority of his father: We were with a man from the Companions of the Prophet (ﷺ) called Mujashi' who belonged to Banu Sulaim. There was a scarcity if goats (in those days). He commanded a man to announce (among the people); so he announced that the Messenger of Allah (ﷺ) used to say: A lamb may be given as full payent for that for which has full-grown animal is payment. Abu Dawud said: His name is Mujashi' b. Mas'ud.

حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا الثَّوْرِيُّ، عَنْ عَاصِمِ بْنِ كُلَيْبٍ، عَنْ أَبِيهِ، قَالَ كُنَّا مَعَ رَجُلٍ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم يُقَالُ لَهُ مُجَاشِعٌ مِنْ بَنِي سُلَيْمٍ فَعَزَّتِ الْغَنَمُ فَأَمَرَ مُنَادِيًا فَنَادَى أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَقُولُ ‏

‏ إِنَّ الْجَذَعَ يُوَفِّي مِمَّا يُوَفِّي مِنْهُ الثَّنِيُّ ‏

‏ ‏.‏ قَالَ أَبُو دَاوُدَ وَهُوَ مُجَاشِعُ بْنُ مَسْعُودٍ ‏.‏
