(136) باب رَمْىِ الْجِمَارِ بِسَبْعِ حَصَيَاتٍ
Narrated `Abdur-Rahman bin Yazid:
When `Abdullah, reached the big Jamra (i.e. Jamrat-ul-Aqaba) he kept the Ka`ba on the left side and Mina on his right side and threw seven pebbles (at the Jamra) and said, "The one on whom Surat-al- Baqara was revealed (i.e. the Prophet) had done the Rami similarly."
