Sahih al-Bukhari · Book 25: Hajj (Pilgrimage) · To say 'Allahu Akbar' on throwing every pebble
Narrated Al-A`mash:
حَدَّثَنَا مُسَدَّدٌ ، عَنْ عَبْدِ الْوَاحِدِ ، حَدَّثَنَا الأَعْمَشُ ، قَالَ سَمِعْتُ الْحَجَّاجَ، يَقُولُ عَلَى الْمِنْبَرِ السُّورَةُ الَّتِي يُذْكَرُ فِيهَا الْبَقَرَةُ، وَالسُّورَةُ الَّتِي يُذْكَرُ فِيهَا آلُ عِمْرَانَ، وَالسُّورَةُ الَّتِي يُذْكَرُ فِيهَا النِّسَاءُ. قَالَ فَذَكَرْتُ ذَلِكَ لإِبْرَاهِيمَ ، فَقَالَ حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ يَزِيدَ أَنَّهُ كَانَ مَعَ ابْنِ مَسْعُودٍ ـ رضى الله عنه ـ حِينَ رَمَى جَمْرَةَ الْعَقَبَةِ، فَاسْتَبْطَنَ الْوَادِيَ، حَتَّى إِذَا حَاذَى بِالشَّجَرَةِ اعْتَرَضَهَا، فَرَمَى بِسَبْعِ حَصَيَاتٍ، يُكَبِّرُ مَعَ كُلِّ حَصَاةٍ، ثُمَّ قَالَ مِنْ هَا هُنَا وَالَّذِي لاَ إِلَهَ غَيْرُهُ قَامَ الَّذِي أُنْزِلَتْ عَلَيْهِ سُورَةُ الْبَقَرَةِ صلى الله عليه وسلم.
I heard Al-Hajjaj saying on the pulpit, "The Sura in which Al-Baqara (the cow) is mentioned and the Sura in which the family of `Imran is mentioned and the Sura in which the women (An-Nisa) is mentioned." I mentioned this to Ibrahim, and he said, `Abdur-Rahman bin Yazid told me, 'I was with Ibn Mas`ud, when he did the Rami of the Jamrat-ul-Aqaba. He went down the middle of the valley, and when he came near the tree (which was near the Jamra) he stood opposite to it and threw seven small pebbles and said: 'Allahu-Akbar' on throwing every pebble.' Then he said, 'By Him, except Whom none has the right to be worshipped, here (at this place) stood the one on whom Surat-al-Baqra was revealed (i.e. Allah's Messenger (ﷺ)).' "
