Muwatta Malik #1098
Game
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّهُ قَالَ رَمَيْتُ طَائِرَيْنِ بِحَجَرٍ وَأَنَا بِالْجُرْفِ، فَأَصَبْتُهُمَا فَأَمَّا أَحَدُهُمَا فَمَاتَ فَطَرَحَهُ عَبْدُ اللَّهِ بْنُ عُمَرَ وَأَمَّا الآخَرُ فَذَهَبَ عَبْدُ اللَّهِ بْنُ عُمَرَ يُذَكِّيهِ بِقَدُومٍ فَمَاتَ قَبْلَ أَنْ يُذَكِّيَهُ فَطَرَحَهُ عَبْدُ اللَّهِ أَيْضًا .
ahya related to me from Malik that Nafi said, "I was at al-Juruf
(near Madina) and threw a stone at two birds, and hit them. One of
them died, and Abdullah ibn Umar threw it away, and then went to
slaughter the other one with an adze. It died before he could
slaughter it, so Abdullah threw that one away as well."
