PROPHET MUHMAAD ( SWS ) NEVER ASKED THEM TO RELEASE THE CAPTIVES.
2.By MY STATEMENT
"In initial period of Islam One may say that the companions of prophet Muhmaad ( sws ) may used to force the slaves for intercourse"
I NEVER MEANT TO SAY THAT PROPHET MUHMAAD ( SWS ) INTIALLY APPROVED RAPE AND THEN FORBADE IT
WHAT I WAS SAYING THAT JUST AS THE COMPANIONS OF PROPHET MUHMAAD ( SWS ) USED TO DRINK ALCOHOL AND HE DIDN'T FORBADE THEM SIMILARLY COMPANIONS OF PROPHET MUHMAAD ( SWS ) MAY USED TO MISTREAT THE SLAVES (EVEN BY FORCING THEM TO INTERCOURSE)
BUT IT IS NOT ACTUALLY ALLOWED TO HARM AND MISTREAT THE SLAVES AND NO ONE CAN DARE TO CHALLENGE
