Sunan Ibn Majah, Chapter: The Chapters on Tribulations

"I came to the Messenger of Allah (saw) during the campaign of Tabuk, when he was in a tent made of leather, so I sat in front of the tent. The Messenger of Allah (saw) said: 'Enter, O Awf.' I said, 'All of me, O Messenger of Allah?' He said: 'All of you.' Then he said: 'O Awf, remember six things (that will occur) before the Hour comes, one of which is my death.' I was very shocked and saddened at that. He said: 'Count that as the first. Then (will come) the conquest of Baitul-Maqdis (Jerusalem); then a disease which will appear among you and cause you and your offspring to die as martyrs and will purify your deeds; then there will be (much) wealth among you, so that if a man were to be given one hundred Dinar he would still be dissatisfied; and there will be tribulation among you that will not leave any Muslim house untouched;* then there will be a treaty between you and the Romans, then they will betray you and march against you with eighty banners, under each of which will be twelve thousand (troops).'"
