Sunan Abi Dawud, Book 10, Hadith 1766 (USC-MSA) ⓘ

Narrated Abdullah ibn Abbas: Sa'id ibn Jubayr said: I said to Abdullah ibn Abbas: AbulAbbas, I am surprised to see the difference of opinion amongst the companions of the Apostle about the wearing of ihram by the Messenger of Allah when he made it obligatory. He replied: I am aware of it more than the people. The Messenger of Allah performed only one hajj. Hence the people differed among themselves. The Messenger of Allah came out (from Medina) with the intention of performing hajj. When he offered two rak'ahs of prayer in the mosque at Dhul-Hulayfah, he made it obligatory by wearing it. At the same meeting, he raised his voice in the talbiyah for hajj, when he finished his two rak'ahs. Some people heard it and I retained it from him. He then rode (on the she-camel), and when it (the she-camel) stood up, with him on its back, he raised his voice in the talbiyah and some people heard it at that moment. This is because the people were coming in groups, so they heard him raising his voice calling the talbiyah when his she-camel stood up with him on its back, and they thought that the Messenger of Allah had raised his voice in the talbiyah when his she-camel stood up with him on its back. The Messenger of Allah proceeded further; when he ascended the height of al-Bayda' he raised his voice in the talbiyah. Some people heard it at that moment. They thought that he had raised his voice in the talbiyah when he ascended the height of al-Bayda'. I swear by Allah, he raised his voice in the talbiyah at the place where he prayed, and he raised his voice in the talbiyah when his she-camel stood up with him on its back, and he raised his voice in the talbiyah when he ascended the height of al-Bayda'. Sa'id (ibn Jubayr) said; He who follows the view of Ibn Abbas raises his voice in talbiyah (and ihram) at the place of is prayer after he finishes two rak'ahs of his prayer.
