It is narrated from Sayyiduna Fadl bin Abbas (may Allah be pleased with him) that on the evening of Arafah and the morning of Muzdalifah, when we set out, the Messenger of Allah (peace and blessings be upon him) said: "Proceed with calmness." And he was also restraining his she-camel from moving fast, until when he entered the valley of Muhassir, the Messenger of Allah (peace and blessings be upon him) said: "Collect pebbles (the size of a chickpea or bean) with which the Jamrah is to be struck." At the same time, the Messenger of Allah (peace and blessings be upon him) was gesturing with his hand in such a way as a person throws a pebble of that size.
