Fadl bin Abbas reported,

He was riding behind the Messenger of Allah ﷺ, and he reported that on the evening of Arafah and the morning of Muzdalifah, as the people were moving on, the Messenger of Allah ﷺ said to them, "Maintain calm." 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." He also said, "The Messenger of Allah ﷺ continued to pronounce 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.
