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. (Using translation from Abū Dāʾūd 2799)
كَانَ رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ ﷺ يُقَالُ لَهُ مُجَاشِعُ بْنُ مَسْعُودٍ السُّلَمِيُّ عَزَّتِ الْغَنَمُ فَأَمَرَ مُنَادِيًا فَنَادَى إِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ الْجَذَعَ مِنَ الضَّأْنِ يُوفِي مِمَّا تُوفِي مِنْهُ الثَّنِيَّةُ
