Sulaiman b. 'Amr b. Ahwas reported on the authority of his mother:I saw the Messenger of Allah (ﷺ) near the Jamrat al-Aqabah (the third or last pillar) riding (on a camel) and I saw a pebble between his fingers. He threw the pebbles and the people also threw (stones at the Jamrah).
حَدَّثَنَا أَبُو ثَوْرٍ، إِبْرَاهِيمُ بْنُ خَالِدٍ وَوَهْبُ بْنُ بَيَانٍ قَالاَ حَدَّثَنَا عَبِيدَةُ، عَنْ يَزِيدَ بْنِ أَبِي زِيَادٍ، عَنْ سُلَيْمَانَ بْنِ عَمْرِو بْنِ الأَحْوَصِ، عَنْ أُمِّهِ، قَالَتْ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عِنْدَ جَمْرَةِ الْعَقَبَةِ رَاكِبًا وَرَأَيْتُ بَيْنَ أَصَابِعِهِ حَجَرًا فَرَمَى وَرَمَى النَّاسُ .
