In this battle at Yamama, Hazrat Umme Ummaarah (ra) also fought with great passion from the start till the very end. She tried to get close to Musaylimah on multiple occasions to fulfil her promise to avenge Hazrat Habeeb’s (ra) martyrdom, but his army kept coming in her way. Meanwhile, Hazrat Khalid Bin Waleed (ra) was after Musaylimah as well but couldn’t get close to him. Around 1,200 Muslims had already been martyred including known companions of the Holy Prophet (sas), Hazrat Zaid Bin Khattaab (ra), Hazrat Abu Huzaifah (ra), Hazrat Saalim (ra), Maula Abu Huzaifah (ra) and Hazrat Sabit Bin Qais (ra). The death toll of the apostates was much higher.
Finally, the fight began to swing in favor of the Muslims. When Musaylimah saw his imminent loss, he asked his followers to protect their prestige if they could. When Hazrat Umme Ummaarah (ra) heard him, she spotted Musaylimah and launched at him. While making her way through the fighting crowd with the help of her spear, she received eleven injuries. One of her hands got cut off at her wrist. When she reached Musaylimah and aimed her spear at him, two more weapons hit him simultaneously and he fell off his horse, fatally wounded. When Hazrat Umme Ummaarah (ra) looked up to see who else had aimed at Musaylimah, she saw her other son Abdullah (ra). Also standing nearby was the person named Wahshi. Both men had aimed their weapons at Musaylimah simultaneously.
