Name and identity
Early biographical records name Sumayra bint Qays as a woman of the Ansar who accepted Islam and pledged allegiance to Muhammad ﷺ. The 82-person series presents its related subject under the name Sümeyra bint Ubeyd; that name is retained as a search alias.

The account of Uhud
Later retellings associate her with a woman who asked whether Muhammad ﷺ had survived Uhud. The cited report calls her a woman of Banu Dinar without naming her. Its transmission has received different assessments, including a weak, interrupted chain; her identification in this story is not established.

Limits of the record
Ibn Sa‘d’s biographical notice records her family and allegiance, but does not provide a full life chronology. Her birth, death, and age are therefore left unknown. The brief record should not be expanded with unsupported stories.
