I say Insha'Allah because We don't know when we will die. Revalation came to the humanity as a warning, but Death will not be call upon us. It will just happen one day. So if I plan to go to school today and do all this stuff, and think about my plans in the future. I leave it to Allah if he will take my last breath today or for the next day, month, or year.

JazakAllahu khairan
