أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا النَّضْرُ، - وَهُوَ ابْنُ شُمَيْلٍ - قَالَ حَدَّثَنَا أَشْعَثُ، - وَهُوَ ابْنُ عَبْدِ الْمَلِكِ - عَنِ الْحَسَنِ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى الظُّهْرَ بِالْبَيْدَاءِ ثُمَّ رَكِبَ وَصَعِدَ جَبَلَ الْبَيْدَاءِ فَأَهَلَّ بِالْحَجِّ وَالْعُمْرَةِ حِينَ صَلَّى الظُّهْرَ .
