Musnad Ahmad 30:2147

'Affan narrated to us, he said: Hammam narrated to us, he said: Qatadah informed us, from 'Abd al-Rahman ibn Adam, from Abu Hurayrah, that the Prophet, peace and blessings of Allah be upon him, said: "The prophets are brothers of 'allat (having the same father but different mothers); their mothers are diverse, but their religion is one. And I am the closest of people to 'Isa ibn Maryam, because there was no prophet between me and him. And he is descending; so when you see him, recognize him: a man of medium stature, inclining toward redness and whiteness, wearing two garments lightly dyed with saffron, as if his head is dripping, even though no moisture has touched it. He will break the cross, kill the swine, and abolish the jizyah. He will call the people to Islam. In his time, Allah will destroy all religions except Islam, and in his time, Allah will destroy the False Messiah (al-Masih al-Dajjal). Then security will settle upon the earth, until lions graze with camels, leopards with cattle, and wolves with sheep. Young boys will play with snakes, and they will not harm them. He will remain for forty years, then he will die, and the Muslims will pray over him."
