It is narrated from Hazrat Umair (may Allah be pleased with him) that I participated in the Battle of Khaybar with my masters. They spoke to the Prophet Muhammad (peace and blessings be upon him) about me, so the Prophet (peace and blessings be upon him) gave an order regarding me, and a sword was hung around my neck (it was so big that) I used to drag it on the ground as I walked. The Prophet (peace and blessings be upon him) was informed that I was a slave, so the Prophet (peace and blessings be upon him) ordered that I should also be given something from the remaining spoils.

It is narrated from Hazrat Umair (may Allah be pleased with him) that I participated in the Battle of Khaybar with my masters. They spoke to the Noble Prophet (peace and blessings be upon him) about me, so the Noble Prophet (peace and blessings be upon him) gave a command regarding me, and a sword was hung around my neck (it was so big that) I used to drag it on the ground as I walked. The Noble Prophet (peace and blessings be upon him) was informed that I was a slave, so the Noble Prophet (peace and blessings be upon him) ordered that I also be given something from the remaining spoils. And I presented before the Noble Prophet (peace and blessings be upon him) an incantation with which I used to perform exorcism on the possessed during the time of ignorance. The Noble Prophet (peace and blessings be upon him) said: Remove such-and-such words from it and perform exorcism with the rest.
