Time is very precious for all of us. Each moment of our life is to be used carefully. This life, as my elders say, is like an ice which is slowly melting away.
This world is darul amal n we've to make our akhirah by collecting more n more good deeds which may please Allah swt to shower his mercy upon us. We know that none of our amal can be as perfect as required standard is. We've to seek mercy of Allah swt instead of depending on our good deeds.
We've wasted our precious hours of our life uselessly. Indeed, This issue must squirm us. Sooner or later we've to leave this world n then we won't be able to add anymore amal in our account. So we must open our eyes before they're closed.
