They replied:
"We bear witness that you have conveyed the message and discharged your ministry."
He then raised his forefinger skywards and then moved it down towards people while saying:
"O Allâh, Bear witness."
He said that phrase thrice. [Sahih Muslim 1/397]
The one who repeated the Prophet’s [pbuh]statements loudly at ‘Arafat was Rabi‘a bin Omaiyah bin Khalaf. [Ibn Hisham 2/605]
As soon as the Prophet [pbuh] had accomplished delivering the speech, the following Qur’ânic verse was revealed to him:
"This day I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion." [Al-Qur'an 5:3]
Upon hearing this verse ‘Umar cried. "What makes you cry?" He was asked. His answer was: "Nothing succeeds perfection but imperfection." [Rahmat-ul-lil'alameen 1/265]
Bilal called for prayer after the speech, and then made the second call. The Prophet [pbuh] performed both of the noon and the afternoon prayers separately, with no prayers in between. He then mounted his she-camel Al-Qaswa’, approached the location of the vigil, directed his face towards Al-Qiblah, kept on standing till sunset when the sky yellow colour vanished a bit and the disc of the sun disappeared. Osamah added that the Prophet [pbuh]moved onward to Muzdalifa. where he observed the sunset and the evening prayers with one ‘First call’ and two ‘second calls’. He did not entertain the Glory of Allâh between the two prayers. Then he lay down till it was dawn prayer time. He performed it with one first call and one second call at almost daybreak time. Mounting on his Al-Qaswa’, he moved towards Al- Mash‘ar Al-Haram. He faced Al-Qiblah and started supplicating: "Allâh is the Greatest. There is no god but Allâh." He remained there till it was clear morning and before the sun rose high, he made his way to Mina. He walked a little and threaded the mid-road leading to the big Jamrah where he stopped and pelted seven pebbles at it saying "Allâh is the Greatest" each time. They were like small pebbles hurled from the bottom of the valley. Then he set off to the sacrificial place, where he sacrificed sixty-three camels with his hands, and asked ‘Ali to slaughter the others, a hundred and thirty-seven altogether. He made ‘Ali share him in Al-Hadi. A piece of meat from each slaughtered animal was ordered to be cooked in a pot and from which both men ate, and drank the soup.
Then the Messenger of Allâh [pbuh] mounted his she-camel and returned to the House where he observed the noon prayer at Makkah and there he came upon the children of ‘Abdul Muttalib were supplying drinking water to people at Zamzam Well. "Draw up water, children of ‘Abdul Muttalib, I would draw up with you if I were not afraid that people would appropriate this honour after me." They handed him a pail of water and he drank to his fill. [Sahih Muslim 1/397-400]
