O mankind ! if ye have a doubt about the Resurrection , ( consider ) that We created you out of dust , then out of sperm , then out of a leech-like clot , then out of a morsel of flesh , partly formed and partly unformed , in order that We may manifest ( our power ) to you ; and We cause whom We will to rest in the wombs for an appointed term , then do We bring you out as babes , then ( foster you ) that ye may reach your age of full strength ; and some of you are called to die , and some are sent back to the feeblest old age , so that they know nothing after having known ( much ) , and ( further ) , thou seest the earth barren and lifeless , but when We pour down rain on it , it is stirred ( to life ) , it swells , and it puts forth every kind of beautiful growth ( in pairs ) .
