Sahih al-Bukhari, Volume 7, Book 68, Hadith 455 (USC-MSA) ⓘ

Narrated `Uqba bin 'Amir Al-Juhani: that the Prophet 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! I get in my share of Jadha'a (a six month old ram)." The Prophet 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 ‏" ‏‏.‏
