It was narrated from Al-Fadl bin Abbas, who rode behind the Messenger of Allah, that:

on the eveing of Arafat and on the morning of Jam (Al-Muzdalifah), when they departed, the Messenger of Allah said to the people: "You must be tranquil," and was reining in his she-came. Then, when he was in Muhassir, which is part of Mina, he said: "You have to look for pebbles the size of date stones of fingertips," with which to stone the Jamrat. And the Messenger of Allah continued to recite the Talbiyah until he stoned Jamrat Al-Aqabah.

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ أَبِي الزُّبَيْرِ، عَنْ أَبِي مَعْبَدٍ، مَوْلَى ابْنِ عَبَّاسٍ عَنِ ابْنِ عَبَّاسٍ، عَنِ الْفَضْلِ بْنِ عَبَّاسٍ، وَكَانَ، رَدِيفَ رَسُولِ اللَّهِ ﷺ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ فِي عَشِيَّةِ عَرَفَةَ وَغَدَاةِ جَمْعٍ لِلنَّاسِ حِينَ دَفَعُوا " عَلَيْكُمُ السَّكِينَةَ " . وَهُوَ كَافٌّ نَاقَتَهُ حَتَّى إِذَا دَخَلَ مُحَسِّرًا وَهُوَ مِنْ مِنًى قَالَ " عَلَيْكُمْ بِحَصَى الْخَذْفِ الَّذِي يُرْمَى بِهِ " . فَلَمْ يَزَلْ رَسُولُ اللَّهِ ﷺ يُلَبِّي حَتَّى رَمَى الْجَمْرَةَ .
