Mukhtasar Muslim

Narrated from Sayyiduna Sa'b bin Jaththamah al-Laithi (may Allah be pleased with him) that he presented the meat of a wild donkey as a gift to the Messenger of Allah (peace and blessings be upon him) while he (the Prophet) was at (the place of) Abwa or Dhuwan, so the Prophet (peace and blessings be upon him) returned it. He says: When the Prophet (peace and blessings be upon him) saw sadness on my face, he said: We did not return it for any other reason, except that we are in the state of Ihram.
