It was narrated from 'Abdullah bin 'Amr, who attributed it to the Messenger of Allah:"There is no person who kills a small bird or anything larger, for no just reason, but Allah will ask him about it." It was said: "O Messenger of Allah, what does 'just reason mean?" He said: "That you slaughters it and eat it, and o not cut off its head and throw it aside,"
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، عَنْ صُهَيْبٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، يَرْفَعُهُ قَالَ " مَنْ قَتَلَ عُصْفُورًا فَمَا فَوْقَهَا بِغَيْرِ حَقِّهَا سَأَلَ اللَّهُ عَزَّ جَلَّ عَنْهَا يَوْمَ الْقِيَامَةِ " . قِيلَ يَا رَسُولَ اللَّهِ فَمَا حَقُّهَا قَالَ " حَقُّهَا أَنْ تَذْبَحَهَا فَتَأْكُلَهَا وَلاَ تَقْطَعْ رَأْسَهَا فَيُرْمَى بِهَا " .
