Sunan an-Nasa'i, Volume 3, Book 24, Hadith 2825 (DarusSalam)

It was narrated that Ibn Abbas said: "As-Sab bin Jaththamah gave the Messenger of Allah the leg of an onager that was dripping with blood when he was in Ihram, at Qudaid, and he returned it to him."

أَخْبَرَنَا مُحَمَّدُ بْنُ قُدَامَةَ، قَالَ حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنِ الْحَكَمِ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ أَهْدَى الصَّعْبُ بْنُ جَثَّامَةَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم رِجْلَ حِمَارِ وَحْشٍ تَقْطُرُ دَمًا وَهُوَ مُحْرِمٌ وَهُوَ بِقُدَيْدٍ فَرَدَّهَا عَلَيْهِ ‏.‏
