Tabari VIII:96 "A raiding party led by Zayd set out against Umm in Ramadan. During it, Umm suffered a cruel death. Zyad tied her legs with rope and then tied her between two camels until they split her in two. She was a very old woman. Then they brought Umm's daughter and Abdallah to the Messenger. Umm's daughter belonged to Salamah who had captured her. Muhammad asked Salamah for her, and Salamah gave her to him."
