Jabir reported God’s messenger as saying, “The whole of ‘Arafa is a place of standing, the whole of Mina is a place of sacrifice, the whole of al-Muzdalifa is a place of standing, and all the passes of Mecca are a thoroughfare and a place of sacrifice.”
‘Amr b. Shu'aib, on his father’s authority, quoted his grandfather as saying that the Prophet said, “The best supplication is that on the day of ‘Arafa, and the best thing which I and the prophets before me have said is, ‘There is no god but God alone who has no partner; to Him belongs the dominion, to Him praise is due, and He is omnipotent’.’’
Tirmidhi transmitted it, and Malik transmitted on the authority of Talha b. ‘Ubaidallah up to “who has no partner.”
Narrated ‘Amr b. ‘Abdallah b. Safwan quoted a maternal uncle of his called Yazid b. Shaiban who said:
We were in a place of standing of ours at ‘Arafa (which ‘Amr indicated was very far away from where the imam was standing), when Ibn Mirba' al-Ansari came to us and told us he had brought this message for us from God’s messenger, “Stand where you are performing your devotions, for you are conforming to an old practice of your father Abraham."
Reported by Tirmidhi, Abu Dawud, Nasa’i, and Ibn Majah.
