وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَامِرِ بْنِ رَبِيعَةَ، قَالَ رَأَيْتُ عُثْمَانَ بْنَ عَفَّانَ بِالْعَرْجِ وَهُوَ مُحْرِمٌ فِي يَوْمٍ صَائِفٍ قَدْ غَطَّى وَجْهَهُ بِقَطِيفَةِ أُرْجُوَانٍ ثُمَّ أُتِيَ بِلَحْمِ صَيْدٍ فَقَالَ لأَصْحَابِهِ كُلُوا ‏.‏ فَقَالُوا أَوَلاَ تَأْكُلُ أَنْتَ فَقَالَ إِنِّي لَسْتُ كَهَيْئَتِكُمْ إِنَّمَا صِيدَ مِنْ أَجْلِي ‏.‏

Yahya related to me from Malik, from Abdullah ibn Abi Bakr, thatAbd ar-Rahman ibn Amir ibn Rabia said, "I once saw Uthman ibn Affan inihram on a hot summer's day at al-Arj,and he had covered his face witha red woollen cloth. Some game-meat was brought to him and he told hiscompanions to eat. They said, 'Will you not eat then?', and he said,'I am not in the same position as you. It was hunted for my sake.'
