What is the message?
The message is to value today: yesterday cannot be changed, and tomorrow is not yet known. Abdul Osama (عبدول أسامة) recites a short saying that puts the present in focus:
Yesterday is history, tomorrow is a mystery, but today is a gift. — Abdul Osama
How should you read it?
The saying uses three simple images. “Yesterday is history” points to what has already happened; “tomorrow is a mystery” acknowledges uncertainty; and “today is a gift” calls attention to the time available now. The video does not give a method or a set of steps. It offers a brief reflection.
What can you do next?
If you find yourself dwelling on the past or worrying about the future, you can use the saying as a reminder to return your attention to today. That is one way to apply the idea, not an instruction given in the video.
