"And what Allah has sent down from the sky of rain, and given life thereby to the earth after its lifelessness," meaning: when it had no vegetation, so He made it grow. "And dispersed therein," meaning: He created. "And His directing of the winds," meaning: their variation, according to the Tafsir of al-Suddi. "And the clouds controlled between the heaven and the earth are signs for a people who use reason," and they are the believers.
