(30:21) And of His signs is that He created for you from yourselves mates that you may find tranquillity in them; and He placed between you affection and mercy. Indeed in that are signs for a people who give thought. (30:22) And of His signs is the creation of the heavens and the earth and the diversity of your languages and your colors. Indeed in that are signs for those of knowledge. (30:23) And of His signs is your sleep by night and day and your seeking of His bounty. Indeed in that are signs for a people who listen. (30:24) And of His signs is [that] He shows you the lightning [causing] fear and aspiration, and He sends down rain from the sky by which He brings to life the earth after its lifelessness. Indeed in that are signs for a people who use reason. (30:25) And of His signs is that the heaven and earth remain by His command. Then when He calls you with a [single] call from the earth, immediately you will come forth.
