The Messenger of Allah ﷺ said, "A group from my nation will continue to stand upon the truth, prevailing over their enemies and overpowering them. Those who oppose them will not harm them, except for the hardships that may afflict them, until the command of Allah comes while they remain in that state."The companions asked, "Messenger of Allah, where are they?"He replied, "In Bayt al-Maqdis and the regions surrounding Bayt al-Maqdis."
