Sahih Bukhari Volume 2, Book 25, Hadith 1749

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ أَنَّهُ انْتَهَى إِلَى الْجَمْرَةِ الْكُبْرَى جَعَلَ الْبَيْتَ عَنْ يَسَارِهِ، وَمِنًى عَنْ يَمِينِهِ، وَرَمَى بِسَبْعٍ، وَقَالَ هَكَذَا رَمَى الَّذِي أُنْزِلَتْ عَلَيْهِ سُورَةُ الْبَقَرَةِ صلى الله عليه وسلم‏

Narrated By '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."
