From his father that he said: "I said: 'O Messenger of Allah! Is there no slaughtering except upon the neck and the throat ?' He said: 'If you stab its thigh it would be accepted to you.'"  

قُلْتُ يَا رَسُولَ اللَّهِ أَمَا تَكُونُ الذَّكَاةُ إِلاَّ فِي الْحَلْقِ وَاللَّبَّةِ قَالَ لَوْ طَعَنْتَ فِي فَخِذِهَا لأَجْزَأَ عَنْكَ قَالَ أَحْمَدُ بْنُ مَنِيعٍ قَالَ يَزِيدُ بْنُ هَارُونَ هَذَا فِي الضَّرُورَةِ قَالَ وَفِي الْبَابِ عَنْ رَافِعِ بْنِ خَدِيجٍ
