Sayyidah Umm Kabshah al-Udhriyyah (may Allah be pleased with her), who was from the Udhrah branch of the Quda'ah tribe, said: I said: O Messenger of Allah! Permit me to go out with such-and-such army. He (peace and blessings be upon him) said: "No." I said: O Messenger of Allah! I do not want to fight; rather, I want to treat the wounded and the sick and give water to the sick. He (peace and blessings be upon him) said: "Were it not for the fear that it would become a custom, and that it would be said that so-and-so woman also went out, I would have given you permission; but you stay behind."
