Great Accomplishments on the Battlefield
Hazrat Anas bin Malik (ra) narrates that the Holy Prophet (sa) stated, “On this day (i.e. on the day of the Battle of Hunayn) whosoever kills a disbeliever, he will be granted the wealth and possessions of the one he kills [as their spoil from the battle].” On that day, Hazrat Abu Talha (ra) killed 20 disbelievers and took their wealth [as spoils from the battle]. Hazrat Abu Talha (ra) saw Hazrat Umm-e-Sulaim (ra) with a dagger in her hand and asked, “O Umm-e-Sulaim (ra), what is the purpose of this?” She replied, “I swear by God! It is my intention that if a disbeliever passes within range, I would strike this dagger and pierce his abdomen.” Hazrat Abu Talha (ra) informed the Holy Prophet (sa) about this incident. This narration is found in Sunan Abi Daud.
