Sahih Muslim Book 54, Hadith 37
I came on the day of Jara`a that a person was (found) sitting. I said: They would shed their blood today. That person said: By Allah. not at all. I said: By Allah, of course, they would do it. He said: By Allah, they would not do it. I said: By Allah, of course, they would do it. He said: By Allah, they would not do it, and I have heard a hadith of Allah's Messenger (ﷺ) which I am narrating to you in this connection. I said: You are a bad seat fellow. I have been opposing you since morning and you are listening to me in spite of the fact that you have heard a hadith from Allah's Apostle (ﷺ) (contrary to my statement). I myself felt that there was no use of this annoyance. (He could tell me earlier that it was a hadith of the Prophet (may peace be upon him], and I would not have opposed him at all.) I turned my face toward him and asked him and he was Hadrat Hudhaifa.
Who would narrate to us (the ahadith pertaining to turmoil) and he reported a hadith similar to these ahadith.
The Last Hour would not come before the Euphrates uncovers a mountain of gold, for which people would fight. Ninety-nine out of each one hundred would die but every man amongst them would say that perhaps he would be the one who would be saved (and thus possess this gold).
