11:25Hud

Allah's Messenger (ﷺ) said, "Noah will be brought (before Allah) on the Day of Resurrection, and will be asked, 'Did you convey the message of Allah?" He will reply, 'Yes, O Lord.' And then Noah's nation will be asked, 'Did he (Noah) convey Allah's message to you?' They will reply, 'No warner came to us.' Then Noah will be asked, 'Who are your witnesses?' He will reply. '(My witnesses are) Muhammad and his followers.' Thereupon you (Muslims) will be brought and you will bear witness." Then the Prophet (ﷺ) recited: 'And thus We have made of you (Muslims) a just and the best nation, that you might be witness over the nations, and the Apostle a witness over you.' (2.143)

Allah's Messenger (ﷺ) said, "Noah will be called on the Day of Resurrection and he will say, 'Labbaik and Sa`daik, O my Lord!' Allah will say, 'Did you convey the Message?' Noah will say, 'Yes.' His nation will then be asked, 'Did he convey the Message to you?' They will say, 'No Warner came to us.' Then Allah will say (to Noah), 'Who will bear witness in your favor?' He will say, 'Muhammad and his followers. So they (i.e. Muslims) will testify that he conveyed the Message. And the Apostle (Muhammad) will be a witness over yourselves, and that is what is meant by the Statement of Allah "Thus We have made of you a just and the best nation that you may be witnesses over mankind and the Apostle (Muhammad) will be a witness over yourselves." (2.143)
