Narrated Abu Sa'eed: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."" [Abu 'Eisa said: This Hadith is [Hasan] 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
