"Abu Al-Darda reported Allah's Messenger (may peace be upon him) as saying: Allah created Adam when He had to create him and He struck his right shoulder and there emitted from it while offspring as if it were white ants. He struck his left shoulder and there emitted from it black offspring as if it were charcoals. He then said (to those who had been emitted) from right (shoulder): For Paradise and I do not mind and then He said to those (who had been emitted) from his left shoulder: They are for Hell and I do not mind.""
