وَعَن أبي العُشَراءِ عَنْ أَبِيهِ
أَنَّهُ قَالَ: يَا رَسُولَ اللَّهِ أَمَا تَكُونُ الذَّكَاةُ إِلَّا فِي الْحَلْقِ وَاللَّبَّةِ؟ فَقَالَ: «لَوْ طَعَنْتَ فِي فَخِذِهَا لَأَجْزَأَ عَنْكَ»
Abul ‘Ushara’* quoted his father as telling that he said, “Is the slaughtering to be done, messenger of God, only in the throat and the upper part of the breast?” He replied, “If you pierced its thigh that would serve you.” *He was Usamah ibn Malik ibn Qahtam (or Qahtam). See Ibn *Abd al-Barr. Istiab, p. 246, No. 10S9. Tirmidhi, Abu Dawud, Nasai, Ibn Majah and Darimi transmitted it.
Abu Dawud said this is the way to slaughter an animal which has fallen into a well, and Tirmidhi said it is in case of necessity.
