The issue is nearing the grave
In his first speech to students after entering Najaf, Imam said: “Be thinking from now, be thinking from youth, every step you take now is towards the grave. Every minute you spend from your noble life, you are getting a little closer to the grave and the place where you will be questioned.
Think about this. The issue is nearing the grave and nobody has given you a deed that will allow you to live for 120 years. It is possible that one dies at 25 years, it is possible that one dies at this very moment, God forbid. You don’t have a deed in your hands; you must pay attention and refine your ethics.
