It is narrated from Hazrat Muadh bin Jabal that he said: The Messenger of Allah, peace and blessings be upon him, said: Six things are signs of the Day of Judgment: my death, the conquest of Bayt al-Maqdis, a person will be given a thousand gold coins and he will dislike it, and there will be such a tribulation that its sorrow will enter every Muslim household, and there will be a death that will afflict people like the 'qa'as' (a chest disease) afflicts goats, and the Romans will betray you; they will come numbering twelve thousand, and under every large banner will be twelve thousand men.
