Be aware and mindful of your actions since you do not know when your time on earth may come to an end; strive to live your life according to Islamic teachings while you still have time left on this earth; prepare yourself for death/the hereafter .

This Hadith is about a narration given by Marwan b. Hakam to three Muslims who were present with him in Medina regarding an event known as "the appearance of the Dajjal". The Hadith also mentions Abdullah bin Amr who reported hearing a similar narration from Prophet Muhammad ﷺ himself but did not mention any details regarding it. This Hadith serves as an important reminder for all believers to be aware of this event which will occur at some point during their lifetime, although no one knows when exactly it will happen or what form it will take place in. It also teaches us to be mindful of our actions since we do not know when our time on earth may come to an end, so we should strive to live our lives according to Islamic teachings while we still have time left on this earth.
