حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا عِيسَى بْنُ يُونُسَ، حَدَّثَنَا الأَعْمَشُ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي سَعِيدٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ فِي حِجَّةِ الْوَدَاعِ ‏"‏ أَلاَ إِنَّ أَحْرَمَ الأَيَّامِ يَوْمُكُمْ هَذَا أَلاَ وَإِنَّ أَحْرَمَ الشُّهُورِ شَهْرُكُمْ هَذَا أَلاَ وَإِنَّ أَحْرَمَ الْبَلَدِ بَلَدُكُمْ هَذَا أَلاَ وَإِنَّ دِمَاءَكُمْ وَأَمْوَالَكُمْ عَلَيْكُمْ حَرَامٌ كَحُرْمَةِ يَوْمِكُمْ هَذَا فِي شَهْرِكُمْ هَذَا فِي بَلَدِكُمْ هَذَا أَلاَ هَلْ بَلَّغْتُ ‏"‏ ‏.‏ قَالُوا نَعَمْ ‏.‏ قَالَ ‏"‏ اللَّهُمَّ اشْهَدْ ‏"‏ ‏.‏
