The Rights of the Non-Combatants in Islam :
Islam has first drawn a clear line of distinction between the combatants and the non-combatants of the enemy country. As far as the non-combatant population is concerned such as women, children, the old and the infirm, etc., the instructions of the Prophet are as follows: "Do not kill any old person, any child or any woman" (Abu Dawud). "Do not kill the monks in monasteries" or "Do not kill the people who are sitting in places of worship" (Musnad of Ibn Hanbal).
During a war, the Prophet saw the corpse of a woman lying on the ground and observed: "She was not fighting. How then she came to be killed?" From this statement of the Prophet the exegetists and jurists have drawn the principle that those who are non-combatants should not be killed during or after the war.
