أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ، عَنْ حَمَّادِ بْنِ سَلَمَةَ، عَنْ أَبِي الْعُشَرَاءِ، عَنْ أَبِيهِ، قَالَ قُلْتُ يَا رَسُولَ اللَّهِ أَمَا تَكُونُ الذَّكَاةُ إِلاَّ فِي الْحَلْقِ وَاللَّبَّةِ قَالَ " لَوْ طَعَنْتَ فِي فَخِذِهَا لأَجْزَأَكَ " .
It was narrated from Abu Ushara' that his father said: "I said: "O Messenger of Allah, is slaughtering only in the throat or upper chest?" He said: 'If you stab it in the thigh, that will suffice,"'(Daif)
