In surah Al - 'asr expained that
By the time
Verily man in loss
Except such as have faith, and do righteous deeds, and join together in the mutual teaching of truth and of patience of contancy.
Actually Time is like a sword. if you neglect the time it will destroy you. when you are just wasting your time, then that time will pass quickly. and the time you have spent only ends in vain. because time is a thing that will not be repeated. when that time has come into force that time will not be repeated again and that will be the past. remember when you wasted time then regret, pain, and misery have been waiting for you.
do not throw your time away. when we have the opportunity to do a good thing then do it. because we do not know tomorrow we can still do good things or not. when you have the opportunity to repent repent immediately do not procrastinate. because we do not know tomorrow we are still on earth or have been under the earth.
