Musnad Ahmad 25:443

'Affan narrated to us, Shu'bah narrated to us, Al-Mughirah ibn al-Nu'man, a sheikh from the Nakha', said: I heard Sa'id ibn Jubayr narrating, he said: I heard Ibn 'Abbas say: The Messenger of Allah (peace and blessings of Allah be upon him) stood among us with an exhortation and said: "O people, you will be gathered to Allah barefoot, naked, and uncircumcised: 'As We began the first creation, We will repeat it. [That is] a promise binding upon Us. Indeed, We will do it.' [Al-Anbiya: 104]. Know that the first of the creation to be clothed on the Day of Resurrection will be Ibrahim. And indeed, people from my Ummah will be brought and taken towards the left. I will say: 'My companions!' It will be said to me: 'You do not know what they innovated after you.' I will then say as the righteous servant said: 'And I was a witness over them as long as I was among them; but when You took me up, You were the Observer over them, and You are, over all things, Witness.' [Al-Ma'idah: 117] up to: 'If You punish them - indeed they are Your servants; but if You forgive them - indeed it is You who is the Exalted in Might, the Wise.' [Al-Ma'idah: 118]. Then it will be said: 'These people did not cease to turn back on their heels since you parted from them.'" Shu'bah said: Sufyan dictated it to him, so Sufyan dictated it to me in his place.
