Musannaf Ibn Abi Shayba 37:405

Al-Fadl ibn Dukayn narrated to us, he said: Tha'labah ibn 'Abbad al-'Abdi, from the people of Basra, narrated to us that he witnessed a sermon one day by Samurah ibn Jundub. He mentioned in his sermon a hadith from the Messenger of Allah (may Allah bless him and grant him peace) that he said: "By Allah, the Hour will not be established until thirty liars emerge, the last of whom is the one-eyed Dajjal, whose left eye is wiped away, as if it were the eye of Abu Yahya—or Yahya—referring to an old man from the Ansar. When he emerges, he will claim that he is Allah. Whoever believes in him, confirms him, and follows him, no righteous deed he previously performed will benefit him. And whoever disbelieves in him and denies him, he will not be punished for any of his previous deeds. He will prevail over the entire earth except the Sacred Precinct (Haram) and Bayt al-Maqdis (Jerusalem). He will besiege the believers in Bayt al-Maqdis. Then Allah will defeat him and his soldiers, to the extent that the stump of a wall and the root of a tree will call out: 'O believer, this is a disbeliever hiding behind me, come and kill him.' He said: 'And that will not happen until you see matters whose significance you will find overwhelming within yourselves, asking one another: Did your Prophet mention any mention of them to you? And until mountains are removed from their positions. Then, following that, will be the seizing (death),' and he gestured with his hand. He said: Then I witnessed another sermon of his, and he mentioned this hadith, neither advancing a word nor delaying it."
