حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلَاءِ ، حَدَّثَنَا مُحَمَّدُ بْنُ إِسْمَاعِيل بْنِ أَبِي فُدَيْكٍ ، عَنْ الضَّحَّاكِ بْنِ عُثْمَانَ ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَرْبُوعٍ ، عَنْ أَبِي بَكْرٍ ، قَالَ : سُئِلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : أَيُّ الْحَجِّ أَفْضَلُ؟ قَالَ :" الْعَجُّ وَالثَّجُّ ".
الْعَجُّ يَعْنِي : التَّلْبِيَةَ، وَالثَّجُّ يَعْنِي : إِهْرَاقَ الدَّمِ
