People are not rich without windfall, and horses are not fat without night grass.

The wicked are afraid of heaven, and the good do not bully it. "People are not rich without windfall, and horses are not fat without night grass", which means that people are not rich without windfall and horses are not fat without night grass. "Evil people are afraid of the sky, and good people don't bully the sky" means that if a person does something bad, although others will be afraid of him, God will not let him go. If a person does a good deed, although he will be bullied by others, God will not treat him badly.
