What was the name of the woman mohammad had killed?

for writing some poetry he didn't like? she wrote '' you obey a stranger who encourages you to murder for . you are greedy men. is there no honor among you? do you expect good from him after the killing of your chiefs. like a hungry man waiting for a cook's broth. upon hearing this, '' mohammad said, will no one rid me of this woman. umayr killed her that night as one of her sons were at her as umayr plunged his sword into her. umayr said she had 5 sons, should i feel guilty? mohammad answered; killing her was as meaningless as two goats ing heads; this is found in ishaq:676. but my notes don't have her name. so who knows her name?
