30:24And of His signs is that He shows you the lightning, causing fear and hope. And He brings down water from the sky, and with it He revives the earth after it was dead. In this are signs for people who understand.

30:28He illustrates an example for you, from your own selves: do you make your servants full partners in the wealth We have given you? Do you revere them as you revere one another? We thus explain the revelations for a people who understand.
