Umayr reported,

I was present at Khaybar with my masters. They spoke to the Messenger of Allah ﷺ about me, and they told him that I was a slave. He ordered that I be given a sword to wear, but when I put it on, I was dragging it along the ground. So he ordered that I be given some of the household goods from the spoils.I showed him an incantation I used to recite over those afflicted with madness, and he instructed me to discard part of it and keep part of it.In another narration, "He gave me some household goods from the spoils but did not allot me a share."

عن عمير مولى أبي اللحم قال

شهدت خيبر مع سادتي، فكلموا في رسول الله ﷺ وكلموه أني مملوك، قال: فأمر بي فقلدت السيف فإذا أنا أجره، فأمر لي بشيء من خرثي المتاع وعرضت عليه رقية كنت أرقي بها المجانين، فأمرني بطرح بعضها، وحبس بعضها. وفي رواية: وأعطاني خرثي المتاع ولم يسهم لي.
