The Messenger of Allah ﷺ distributed sacrificial animals among his Companions. He gave me a kid (of less than a year). I took it to him and said: This is a kid. He said: Sacrifice it. so I sacrificed it. (Using translation from Abū Dāʾūd 2798)
قَسَّمَ رَسُولُ اللهِ ﷺ فِي أَصْحَابِهِ غَنَمًا لِلضَّحَايَا فَأَعْطَانِي عَتُودًا جَذَعًا فَرَجَعْتُ إِلَيْهِ فَقُلْتُ يَا رَسُولَ اللهِ إِنَّهُ جَذَعٌ فَقَالَ «ضَحِّ بِهِ» فَضَحَّيْتُ بِهِ
