Sahih al-Bukhari 73:3
Narrated `Uqba bin 'Amir Al-Juhani:
that the Prophet (ﷺ) distributed among his companions some animals for sacrifice (to be slaughtered on `Id-al-Adha). `Uqba's share was a Jadha'a (a six month old goat). `Uqba said, "O Allah's Messenger (ﷺ)! I get in my share of Jadha'a (a six month old ram)." The Prophet (ﷺ) said, "Slaughter it as a sacrifice."

حَدَّثَنَا مُعَاذُ بْنُ فَضَالَةَ، حَدَّثَنَا هِشَامٌ، عَنْ يَحْيَى، عَنْ بَعْجَةَ الْجُهَنِيِّ، عَنْ عُقْبَةَ بْنِ عَامِرٍ الْجُهَنِيِّ، قَالَ قَسَمَ النَّبِيُّ صلى الله عليه وسلم بَيْنَ أَصْحَابِهِ ضَحَايَا، فَصَارَتْ لِعُقْبَةَ جَذَعَةٌ. فَقُلْتُ يَا رَسُولَ اللَّهِ صَارَتْ جَذَعَةٌ. قَالَ " ضَحِّ بِهَا ".
