How beautiful it is that Islam does not enforce you to just sit all day in remembrance to gain great reward. You can simply recite these four words and receive immense reward.
Again putting emphasis on the quality and not the quantity. Do ponder over the translation of these four words and try to catch the powerful meaning and you will see how these are heavier on the scale than a whole morning’s worth of regular remembrance.
