Yazid ibn Shayban said: We were in a place of stationing at Arafat which Amr (ibn Abdullah) thought was very far away from where the imam was stationing, when Ibn Mirba' al-Ansari came to us and told (us): I am a messenger for you from the Messenger of Allah (ﷺ). He tells you: Station where you are performing your devotions for you are an heir to the heritage of Abraham.
