Musnad Ahmad 30:2504

Yahya narrated to us, from Ibn Abi Arubah, who said: Qatadah narrated to us, from Abd al-Rahman ibn Adam, from Abu Hurayrah, from the Prophet, peace and blessings of Allah be upon him, who said: "The prophets are brothers of different mothers: their religion is one, and their mothers are various. 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: he is a man of medium stature, inclining toward redness and whiteness, with straight hair as if his head is dripping, even though no moisture has touched it. He will be between two light yellow garments. He will break the cross, kill the swine, abolish the jizyah, and nullify the religions, until Allah destroys in his time all religions except Islam. And Allah will destroy in his time the False Messiah, the Liar. Security will fall upon the earth until camels will graze with lions together, leopards with cattle, and wolves with sheep. Young boys and children will play with snakes, and they will not harm one another. He will remain as long as Allah wills him to remain, then he will die, and the Muslims will pray over him and bury him."
