Sunan Abi Dawud 1966
Narrated Sulaiman b. 'Amr b. al-Ahwas:
On the authority of his mother: I saw the Messenger of Allah (ﷺ) throwing pebbles at the jamrah from the botton of wadi (valley) while he was riding (on a camel). He was uttering the takbir (Allah is most great) with each pebble. A man behind him was shading him. I asked about the man. They (the people) said: He is al-Fadl b. al-'Abbas. The people crowded. The Prophet (ﷺ) said: 'O people, do not kill each other ; when you throw pebbled at the jamrah, throw small pebbles.
حَدَّثَنَا إِبْرَاهِيمُ بْنُ مَهْدِيٍّ، حَدَّثَنِي عَلِيُّ بْنُ مُسْهِرٍ، عَنْ يَزِيدَ بْنِ أَبِي زِيَادٍ، أَخْبَرَنَا سُلَيْمَانُ بْنُ عَمْرِو بْنِ الأَحْوَصِ، عَنْ أُمِّهِ، قَالَتْ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَرْمِي الْجَمْرَةَ مِنْ بَطْنِ الْوَادِي وَهُوَ رَاكِبٌ يُكَبِّرُ مَعَ كُلِّ حَصَاةٍ وَرَجُلٌ مِنْ خَلْفِهِ يَسْتُرُهُ فَسَأَلْتُ عَنِ الرَّجُلِ فَقَالُوا الْفَضْلُ بْنُ الْعَبَّاسِ وَازْدَحَمَ النَّاسُ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ يَا أَيُّهَا النَّاسُ لاَ يَقْتُلْ بَعْضُكُمْ بَعْضًا وَإِذَا رَمَيْتُمُ الْجَمْرَةَ فَارْمُوا بِمِثْلِ حَصَى الْخَذْفِ ‏"‏ ‏.‏
