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.
