Yazid ibn Hurmuz narrated : Najdah Hururi wrote to Sayyidina ibn Abbas (RA) asking him whether Allahs Messenger (SAW) took women along to battles and did he give them a share in the booty. So, Sayyidina Ibn Abbas wrote to him: You have wrote to me asking if Allah’s Messenger (SAW) took women along in battles. Yes, he did take them with him and they attended to the sick. They were presented from the booty (as reward). As for a share, he did not fix any share for them.
[Muslim 1812]
