"Prevent your boys from tying the birds for the sake of killing them, as I have heard the Prophet ﷺ forbidding the killing of an animal or other living thing after tying them."  

أَنَّهُ دَخَلَ عَلَى يَحْيَى بْنِ سَعِيدٍ وَغُلاَمٌ مِنْ بَنِي يَحْيَى رَابِطٌ دَجَاجَةً يَرْمِيهَا فَمَشَى إِلَيْهَا ابْنُ عُمَرَ حَتَّى حَلَّهَا ثُمَّ أَقْبَلَ بِهَا وَبِالْغُلاَمِ مَعَهُ فَقَالَ ازْجُرُوا غُلاَمَكُمْ عَنْ أَنْ يَصْبِرَ هَذَا الطَّيْرَ لِلْقَتْلِ فَإِنِّي سَمِعْتُ النَّبِيَّ ﷺ نَهَى أَنْ تُصْبَرَ بَهِيمَةٌ أَوْ غَيْرُهَا لِلْقَتْلِ
