‘Abd Allaah bin (mas’ud) said “A woman was found slain in one of the battles of the Apostle of Allaah(ﷺ). The Apostle of Allaah(ﷺ) forbade to kill women and children.
Sunan Abi Dawud Book 15, Hadith 192
← Previous Hadith Al-Hayyaj ibn Imran ibn Husayn reported that a slave of Imran ran away. He took a vow to Allah that if he overpowers him, he will cut off his head. He then sent me (to Samurah ibn Jundub) to ask him about this question for him. I came to Samurah ibn Jundub and asked him. He said: The Messenger of Allah (ﷺ) used to exhort us to give alms (sadaqah) and forbid us to mutilate (a slain). I then came to Imran ibn Husayn and asked him. He said: The Messenger of Allah (ﷺ) used to exhort us to give alms (sadaqah) and forbid us to mutilate (a slain).

Sunan Abi Dawud Book 15, Hadith 191 Next Hadith → When we were with the Messenger of Allah (ﷺ) on an expedition, he saw some people collected together over something and sent a man and said: See, what are these people collected around? He then came and said: They are round a woman who has been killed. He said: This is not one with whom fighting should have taken place. Khalid ibn al-Walid was in charge of the van; so he sent a man and said: Tell Khalid not to kill a woman or a hired servant.
