Fadl bin Abbas, who rode behind the Messenger of Allah ﷺ on his mount, reported that on the evening at Arafah and the morning at Muzdalifah, when the people were moving on, the Messenger of Allah ﷺ said to them, "Maintain calm and tranquility." He was holding back his she-camel until he entered Muhassir, which is part of Mina.He said, "Use pebbles the size of those flicked between the fingers for stoning the jamrah."Fadl also said, "The Messenger of Allah ﷺ continued reciting the talbiyah until he stoned the jamrah."
عن الفضل بن عباس- وكان رديف رسول الله ﷺ أنه قال في عشية عرفة وغداة جمع للناس حين دفعوا: عليكم بالسكينة، وهو كاف ناقته حتى دخل محسرا. وهو من منى. قال: عليكم بحصى الخذف الذي يرمى به الجمرة. وقال: لم يزل رسول الله ﷺ يلبي حتى رمي الجمرة.
Muslim narrated it in the book of Hajj (1282) via Layth, from Abu Zubayr, from Abu Mabad the freed slave of Ibn Abbas, from Ibn Abbas, from Fadl bin Abbas, as mentioned. He also narrated it via Ibn Jurayj, who said, "Abu Zubayr informed me," with this same chain, except that he did not mention in the hadith, "The Messenger of Allah ﷺ kept saying the talbiyah until he threw the pebbles at the jamrah." He added in his account, "And the Prophet ﷺ was gesturing with his hand the way a person does when flicking something."His words, "with pebbles the size used for flicking," refer to something about the size of a bean, and khadhf (flicking) means placing the pebble between the thumb and index finger and then flinging it with the thumb.
