Yazid bin Humruz said “Najdah Al Hururi wrote to Ibn ‘Abbas asking him whether the women participated in battle along with the Apostle of Allaah ﷺ and whether they were allotted a share from the spoils. I (Yazid bin Hurmuz) wrote a letter on behalf of Ibn ‘Abbas to Najdah. They participated in the battle along with the Apostle of Allaah ﷺ, but no portion (from the spoils) was allotted to them, they were given only a little of it.
