Translation:

56. Do no mischief on the earth after it hath been set in order but call on Him with fear and longing (in your hearts): for the mercy of Allah is (always) near to those who do good.

Notes (Tafseer)

1034. The man who prays with humility and earnestness finds the ground prepared by Allah for his spiritual advancement. It is all set in order, and cleared of weeds. He does not, like the wicked, upset that order, to introduce evil or mischief into it.

1035. Fear and longing: the fear of Allah is really a fear lest we should diverge from His Will, or do anything which would not be pleasing to Him: unlike ordinary fear, it therefore brings us nearer to Allah, and in fact nourishes our longing and desire for Him.
