Jami` at-Tirmidhi Book 49, Hadith 6
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."
"They said: 'O Messenger of Allah (ﷺ)! When was the Prophethood established for you?' He said: 'While Adam was between (being) soul and body.'"
that the Messenger of Allah (ﷺ) said: "I am the first for whom the earth will be split, and then I will be adorned with garments from the garments of Paradise. Then I will stand at the right of the Throne. No one from the creation will in that place other than I."
