“A Prophet will come accompanied by two men, and a Prophet will come accompanied by three, and (some will come) with more or less than that. It will be said to him: ‘Did you convey the message to your people?’ And he will say: ‘Yes.’ Then his people will be called and it will be said: ‘Did he convey the message to you?’ They will say: ‘No.’ Then it will be said: ‘Who will bear witness for you?’ He will say: ‘Muhammad and his nation.’ So the nation of Muhammad will be called and it will be said: ‘Did this man convey the message?’ They will say: ‘Yes.’ He will say: ‘How did you know that?’ They will say: ‘Our Prophet told us that the Messengers had conveyed the message, and we believed him.’ This is what Allah says: “Thus We have made you, a just (and the best) nation, that you be witnesses over mankind and the Messenger (Muhammad (ﷺ)) be a witness over you.’”

Allah's Messenger (ﷺ) said, "Noah and his nation will come (on the Day of Resurrection and Allah will ask (Noah), "Did you convey (the Message)?' He will reply, 'Yes, O my Lord!' Then Allah will ask Noah's nation, 'Did Noah convey My Message to you?' They will reply, 'No, no prophet came to us.' Then Allah will ask Noah, 'Who will stand a witness for you?' He will reply, 'Muhammad and his followers (will stand witness for me).' So, I and my followers will stand as witnesses for him (that he conveyed Allah's Message)." That is, (the interpretation) of the Statement of Allah: "Thus we have made you a just and the best nation that you might be witnesses Over mankind .." (2.143)

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)

that about Allah's saying: Thus we have made you a Wasata nation (2:143) - the Prophet (ﷺ) said: "The meaning of Wasata is just." Sahih. (Another chain) From Abu Sa'eed who narrated that: "The Messenger of Allah a said: 'Nuh will be called and it will be said: "Did you deliver (the Message)? "He will say: "Yes" and his people will be called and it will be said: "Did he call you?" They will say: "No warner came to us. No one came to us.' It will be said: "Who will testify for you?" So it is said: "Muhammad and his Ummah (community)." He (ﷺ) said: You will be brought to testify that he delivered (the Message) and that is His saying: Thus, we have made you a Wasata nation that you will be witnesses over mankind and the Messenger (Muhammad) will be a witness over you.' And Al-Wasat is "Just." (Sahih) Abu 'Eisa said: This Hadith is Hasan Sahih.
