Musnad Ahmad 1034:188

'Abd al-Razzaq narrated to us, Ma'mar informed us, from Qatadah, from Nasr ibn 'Asim al-Laythi, from Khalid ibn Khalid al-Yashkuri, who said: I went out at the time Tustar was conquered until I arrived in Kufa. I entered the mosque, and there I was in a circle containing a man, a sturdy man, with beautiful teeth, in whom it was recognized that he was one of the men of the people of the Hijaz. He said: I said, "Who is the man?" The people said, "Do you not know him?" I said, "No." They said, "This is Hudhayfah ibn al-Yaman, the companion of the Messenger of Allah, may Allah bless him and grant him peace." He said: So I sat down, and he was speaking to the people. He said: "Indeed, the people used to ask the Messenger of Allah, may Allah bless him and grant him peace, about the good, and I used to ask him about the evil." The people disapproved of that from him, so he said to them: "I will inform you of what you disapproved of regarding that. Islam came when it came, and a matter came that was not like the matter of the Jahiliyyah. I had been given an understanding of the Qur'an, so men would come and ask about the good, and I would ask him about the evil." I said: "O Messenger of Allah, will there be evil after this good, just as there was evil before it?" He said: "Yes." I said: "What is the protection, O Messenger of Allah?" He said: "The sword." I said: "And will there be any remainder after this sword?" He said: "Yes, there will be an emirate upon impurities and a truce upon smoke." I said: "Then what?" He said: "Then the callers of misguidance will arise. If Allah has a caliph on the earth on that day, and he lashes your back and takes your wealth, then adhere to him. Otherwise, die while you are biting onto the root of a tree." I said: "Then what?" He said: "The Dajjal will emerge after that, with him a river and a fire. Whoever falls into his fire, his reward becomes mandatory and his sin is removed. And whoever falls into his river, his sin becomes mandatory and his reward is removed." I said: "Then what?" He said: "Then the foal will be born, and it will not be ridden until the Hour is established." (The term "sturdy man" means: lean. His saying "What is the protection from it?" he said: "The sword." Qatadah used to apply it to the apostasy that occurred in the time of Abu Bakr. His saying "upon impurities" means: upon filth. And "a truce" means: peace. And his saying "upon smoke" means: upon grudges.) It was said to 'Abd al-Razzaq: "From whom is the interpretation?" He said: "From Qatadah, he claimed."
