Hadrat Amr-bin-al-as (Radi Allaahu Ta’ala Anhu) narrated: The Messenger of ALLAH (Sallallahu Alaihi Wa Sallam) delivered a sermon one day. In it he said, “Listen and remember that this world is temporary and momentary deal which is ready and available for the time being (it has no real worth or value). So everyone, good or bad, has a share in it and all are fed by it. Believe it firmly that the Day of Reckoning will come at its appointed time. This is an inevitable fact and on this day the Almighty Sovereign will decree reward or punishment to all (according to their deeds).
Remember, all good and every kind of comfort is in Paradise and all evil and every kind of evil is in Hell. So beware whatever you do, do it fearing ALLAH and keep its reaction in the Hereafter in view. Believe it that you will be presented before ALLAH with all your deeds and who has done an atom of good will see it and whoever has done an atom of evil will see it too. [Musnad Imam Shafii, Ma’ariful Hadis]
