حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الرَّحِيمِ، أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ بْنِ سَعْدٍ، عَنِ ابْنِ أَخِي ابْنِ شِهَابٍ، عَنْ عَمِّهِ ابْنِ شِهَابٍ، عَنْ سَالِمٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " كُلُوا مِنَ الأَضَاحِيِّ ثَلاَثًا ". وَكَانَ عَبْدُ اللَّهِ يَأْكُلُ بِالزَّيْتِ حِينَ يَنْفِرُ مِنْ مِنًى، مِنْ أَجْلِ لُحُومِ الْهَدْىِ.
