Jami` at-Tirmidhi Book 49, Hadith 5
"They said: 'O Messenger of Allah (ﷺ)! When was the Prophethood established for you?' He said: 'While Adam was between (being) soul and body.'"
"Al-Abbas came to the Messenger of Allah (ﷺ), and it is as if he heard something, so the Prophet (ﷺ) stood upon the Minbar and said: 'Who am I?' They said: 'You are the Messenger of Allah, upon you be peace.' He said: 'I am Muhammad bin 'Abdullah bin 'Abdul-Muttalib, indeed Allah created the creation, and He put me in the best of them, then He made them into two groups, so He put me in the best group of them, then He made them into tribes, so He put me in the best of them in tribe, then He made them into houses, so He put me in the best of them in tribe and lineage.'"
that the Messenger of Allah (ﷺ) said: "I am the first of the people to appear upon their being resurrected, and I am their spokesman whenever they gather, and I am the one that gives them glad tidings whenever they give up hope. And the Banner of Praise will be in my hand that day, and I am the most noble of the children of Adam with my Lord, and I am not boasting."
