أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَنْبَأَنَا النَّضْرُ، قَالَ حَدَّثَنَا أَشْعَثُ، عَنِ الْحَسَنِ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى الظُّهْرَ بِالْبَيْدَاءِ ثُمَّ رَكِبَ وَصَعِدَ جَبَلَ الْبَيْدَاءِ وَأَهَلَّ بِالْحَجِّ وَالْعُمْرَةِ حِينَ صَلَّى الظُّهْرَ .
It was narrated from Anas: That the Messenger of Allah prayed Zuhr in Al-Baida', then he mounted and rode up the mountain of Al-Baida', and he began the Talbiyah for Hajj and 'Umar when he had prayed Zuhr.
