In the battle- field of HUNINE, the prophet saw a woman of the enemy who was slain! He asked who did that, and he was informed that KHALID- IBN- VALID killed her. Seeing that forbidden and unlawful murder, the prophet became angry and said to his page: ``Go you as quick as possible to Khalid, and tell him that; `Allah Has prohibited the slaughter of women, children, and the weak in the battles.'' Among the captives, there was a woman, named SHEMط, who claimed to be the Foster- sister of Mohammad. No one believed her, yet they brought her to the prophet, and she gave evidences and proved that she was the daughter of Halimeh the prophet's wet- nurse in childhood. Then the prophet spread his robe on the ground and offered her to sit down. Then the prophet gave her two options: either to live with Muslims respectfully, or to join her clan, which Shema chose the latter. WHO KILLED THAT WOMAN?
