Sahih Muslim , Book 7, Hadith 2704 (USC-MSA) ⓘ
Ibn 'Abbas (Allah be pleased with them) reported that al-Sa'b b. Jaththama presented to the Messenger of Allah a wild ass as he was in a state of Ihram, and he returned it to him saying: If we were not in a state of Ihram, we would have accepted it from you.
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ حَبِيبِ بْنِ أَبِي ثَابِتٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، - رضى الله عنهما - قَالَ أَهْدَى الصَّعْبُ بْنُ جَثَّامَةَ إِلَى النَّبِيِّ صلى الله عليه وسلم حِمَارَ وَحْشٍ وَهُوَ مُحْرِمٌ فَرَدَّهُ عَلَيْهِ وَقَالَ " لَوْلاَ أَنَّا مُحْرِمُونَ لَقَبِلْنَاهُ مِنْكَ " .
