you can see that the unjust are afraid of the consequences of their deeds which will inevitably strike them. however the righteously striving believers will live in the gardens wherein they will have whatever they want from their lord. this is certainly the greatest reward.
ترى الظالمين مشفقين مما كسبوا وهو واقع بهم والذين آمنوا وعملوا الصالحات في روضات الجنات لهم ما يشاءون عند ربهم ذلك هو الفضل الكبير
