An-Nisaa, Chapter #4, Verse #24) ) And all married women (are forbidden unto you) save those (captives) whom your right hands possess. It is a decree of Allah for you. Lawful unto you are all beyond those mentioned, so that ye seek them with your wealth in honest wedlock, not debauchery. And those of whom ye seek content (by marrying them), give unto them their portions as a duty. And there is no sin for you in what ye do by mutual agreement after the duty (hath been done). Lo!

Quran 47:4 When you meet the unbelievers, smite their necks, then, when you have made wide slaughter among them, tie fast the bonds; then set them free, either by grace or (by) ransom, till the war lays down its loads.

And those who are slain in the way of God, He will not send their works astray. Quran 24:
