حَدَّثَنَا سُلَيْمَانُ بْنُ دَاوُدَ أَبُو الرَّبِيعِ، حَدَّثَنَا فُلَيْحٌ، عَنِ الزُّهْرِيِّ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ أَبَا بَكْرٍ الصِّدِّيقَ ـ رضى الله عنه ـ بَعَثَهُ فِي الْحَجَّةِ الَّتِي أَمَّرَهُ النَّبِيُّ صلى الله عليه وسلم قَبْلَ حَجَّةِ الْوَدَاعِ يَوْمَ النَّحْرِ فِي رَهْطٍ يُؤَذِّنُ فِي النَّاسِ لاَ يَحُجُّ بَعْدَ الْعَامِ مُشْرِكٌ وَلاَ يَطُوفُ بِالْبَيْتِ عُرْيَانٌ‏.‏
