Leave the Future Alone

“The Event (The hour of punishment) ordained by Allah will come to pass so seek not to hasten it.” (Surah An-Nahl:1)
Be not hasty and rushed for things that have yet to come to pass. Do you think it wise to pick fruits before they become ripe?
Tomorrow is non-existent having no reality today, so why should we busy ourselves with it? Why should we have apprehensions about future disasters?
Why should we be engrossed by these thoughts, especially since we do not know whether we will even see tomorrow or not?
The important thing to know is that tomorrow is from the world of the unseen, a bridge that we do not cross until it comes. Who knows, perhaps we might never reach the bridge, or the bridge might collapse before we reach it, or we may actually reach it and cross safely. For us to be engrossed in expectations about the future is looked down upon in our religion since it leads to our having a long-term attachment to this world, an attachment that the good believer shuns.
Many people of this world are unduly fearful of future poverty, hunger, disease, and disaster; such thinking is inspired by devil.
“Satan threatens you with poverty and orders you to commit Fahshah (evil deeds, sins etc.), whereas Allah promises you Forgiveness from Himself and Bounty Allah is All-Embracing, All-knowing.” (Surah Al-Baqarah; 2:268)
Many are those who cry because they see themselves starving tomorrow, falling sick after a month, or because they fear that the world will come to an end after a year or so. Someone who has no clue as to when he will die (which is all of us) should not busy himself with such thoughts. Since we are absorbed in the toils of today, leave tomorrow until it comes. Beware of becoming unduly attached to future prospects in this world.
Once Prophet Mohammad (Peace be upon him) asked, about the duration of life. A companion replied, “I don’t know wether I will offer next prayer or not” Prophet Mohammad (Peace be upon him) replied, “I don’t know wether I will take next breath or not” 
(Meaning or Hadith)This is the duration of life. So instead of worrying about our tomorrow we should be worried about the Day of Judgement and the Life after that.
