Anas bin Malik reported,

Umm Sulaym took up a dagger on the day of Hunayn and kept it with her. Abu Talha saw her and said, "Messenger of Allah, this is Umm Sulaym, and she has a dagger with her."The Messenger of Allah ﷺ asked her, "What is this dagger for?"She replied, "I took it so that if any of the polytheists comes near me, I will rip open his belly with it."The Messenger of Allah ﷺ began to laugh.She said, "Messenger of Allah, kill those who are with us from among the freed ones, for they fled and abandoned you."The Messenger of Allah ﷺ said, "Umm Sulaym, Allah has already sufficed and done well."

عن أنس

أن أم سليم اتخذت يوم حنين خنجرا فكان معها فرآها أبو طلحة فقال يا رسول الله هذه أم سليم معها خنجر فقال لها رسول الله ﷺ ما هذا الخنجر قالت اتخذته إن دنا مني أحد من المشركين بقرت به بطنه فجعل رسول الله ﷺ يضحك قالت يا رسول الله اقتل من بعدنا من الطلقاء انهزموا بك فقال رسول الله ﷺ يا أم سليم إن الله قد كفى وأحسن
