وَأَخِى هَٰرُونُ هُوَ أَفْصَحُ مِنِّى لِسَانًۭا فَأَرْسِلْهُ مَعِىَ رِدْءًۭا يُصَدِّقُنِىٓ ۖ إِنِّىٓ أَخَافُ أَن يُكَذِّبُونِ
My brother Aaron is more eloquent than me in speech. Therefor send him with me as a helper to confirm me. Lo! I fear that they will give the lie to me.

Sahih al-Bukhari
Holding Fast to the Qur'an and Sunnah
Chapter: “Thus We have made you a just nation…”
Narrated Abu Sa`id Al-Khudri:
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)
