Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that on the day of Hunayn, Umm Sulaym was with Abu Talhah. Umm Sulaym also had a dagger with her. Abu Talhah asked: "Umm Sulaym! What is this with you?" She said: "I have picked this up so that if any disbeliever comes near me, I will rip open his belly and take out his intestines." Abu Talhah said: "O Messenger of Allah! Are you hearing what Umm Sulaym is saying? She is saying such and such." I said: "O Messenger of Allah! When they are defeated and become uncontrolled, I will kill them." The Prophet (peace and blessings be upon him) said: "Umm Sulaym! Indeed, Allah the Mighty and Majestic has sufficed us and has done excellently."
