The order of the Prophet ﷺ that people should be calm and patient on proceeding (from 'Arafat) and the waving of his lash towards them — Sahih al-Bukhari 1671

I proceeded along with the Prophet (ﷺ) on the day of `Arafat (9th Dhul-Hijja). The Prophet (ﷺ) heard a great hue and cry and the beating of camels behind him. So he beckoned to the people with his lash, "O people! Be quiet. Hastening is not a sign of righteousness."
