Al-A 'mash said :

"I head Al-Hajjaj say: 'Do not say Surat Al-Baqarah, say: 'The Surah in which the cow (Al-Baqarah) is mentioned."' I mentioned that to Ibrahim, and he said: "Abdur-Rahman bi Yazdi told me, that he was with 'Abdullah when he stoned Jamratul 'Aqabah. He went down the middle of the valley, stood opposite it - meaning the Jamrah - and throew seven pebbiles at it, saying the Takbir with each pebble. I said; "Some people climbed the mountain." He said: "Here - by the One beside Whom there is no other God - is the place where the one to whom Surat Al-Baqarah was revelated stoned."

أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا ابْنُ أَبِي زَائِدَةَ، قَالَ حَدَّثَنَا الأَعْمَشُ، سَمِعْتُ الْحَجَّاجَ، يَقُولُ لاَ تَقُولُوا سُورَةُ الْبَقَرَةِ قُولُوا السُّورَةُ الَّتِي يُذْكَرُ فِيهَا الْبَقَرَةُ ‏.‏ فَذَكَرْتُ ذَلِكَ لإِبْرَاهِيمَ فَقَالَ أَخْبَرَنِي عَبْدُ الرَّحْمَنِ بْنُ يَزِيدَ أَنَّهُ كَانَ مَعَ عَبْدِ اللَّهِ حِينَ رَمَى جَمْرَةَ الْعَقَبَةِ فَاسْتَبْطَنَ الْوَادِيَ وَاسْتَعْرَضَهَا يَعْنِي الْجَمْرَةَ فَرَمَاهَا بِسَبْعِ حَصَيَاتٍ وَكَبَّرَ مَعَ كُلِّ حَصَاةٍ فَقُلْتُ إِنَّ أُنَاسًا يَصْعَدُونَ الْجَبَلَ ‏.‏ فَقَالَ هَا هُنَا وَالَّذِي لاَ إِلَهَ غَيْرُهُ رَأَيْتُ الَّذِي أُنْزِلَتْ عَلَيْهِ سُورَةُ الْبَقَرَةِ رَمَى ‏.‏
