Surah 7. Al-A'raf, Ayah 56

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.

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.
