do the hadiths tell us when certain verses were send down?

sura 4:24 all married women are forbidden unto you except those captives your right hand posses. it is a decree from allah for you.,, here is the reason the apostle of allah sent a military expedition to awtas on the occasion of the battle of hunain. they defeated them and took captives.,some of the campanions of the apostle of allah were reluctant to have intercourse with the female captives in the presence of their husbands, who were unbelievers, so allah sent gabrial down to earth and told mohammad all married women are forbidden unto you except those whom your right hand possess''. so the men raped the women as their husbands watch... how many people find this example wonderful?
