Musannaf Ibn Abi Shaybah

Hazrat Yahya bin Saeed narrates that it is reported about Hazrat Abu Bakr bin Amr bin Hazm that a girl was brought to him who had not yet reached the age of menstruation. She had caught hold of a boy, killed him, and taken away whatever he had with him. When he saw that this girl had acted like adults, he gave the order regarding her, so she was executed.
