"The Muslim narrator (who happens to be Muhammad's adopted son) sees the women trying to escape (following the massacre of their men) and cuts off their route by shooting an arrow into their path. These aren't women trying to seek refuge with the Muslims. They are trying to avoid capture by the Muslim.
The same hadith goes on to recount that Muhammad personally demanded one of the captured women for his own use:
I drove them along until I brought them to Abu Bakr who bestowed that girl upon me as a prize. So we arrived in Medina. I had not yet disrobed her when the Messenger of Allah (may peace be upon him) met me in the street and said: “Give me that girl.” (Sahih Muslim 4345)
The prophet of Islam and his companions used war to collect women for personal sexual use and for trading. Unless she was arbitrarily declared as someone's wife, the woman became a sex slave. In no case was her fate tied to anything that she had personally done, nor was she given a choice about her future."
