Allah said, {And of those whom We have created}, in reference to some nations, {a community}, that stands in truth, in words and action, {who guides (others) with the truth}, they proclaim it and call to it, {and establishes justice therewith}, adhere to it themselves and judge by it. It was reported that this Ayah refers to the Ummah of Muhammad.
In the Two Sahihs, it is recorded that Mu'awiyah bin Abi Sufyan said that the Messenger of Allah said, "There will always be a group of my Ummah who are apparent on the Truth, unabated by those who fail or oppose them, until the (Last) Hour commences."
In another narration, the Messenger said, "Until Allah’s command (the Last Hour) comes while they are still like this ." and in yet another narration, "And they will dwell in Ash-Sham (Greater Syria)."
