"There is no person who kills a small bird or anything larger for no just reason, but Allah, the Mighty and Sublime, will ask him about it." It was said: "O Messenger of Allah, what does just reason;' mean?" Her said: "That you slaughter it and eat it, and do not cut off its head and throw it aside." (Using translation from Nasāʾī 4349)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَا مِنْ إِنْسَانٍ يَقْتُلُ عُصْفُورًا فَمَا فَوْقَهَا بِغَيْرِ حَقِّهَا إِلَّا سَأَلَهُ اللهُ عَنْهَا» قِيلَ يَا رَسُولَ اللهِ وَمَا حَقُّهَا؟ قَالَ «يَذْبَحُهَا فَيَأْكُلُهَا وَلَا يَقْطَعُ رَأْسَهَا فَيَرْمِي بِهَا»
