Family & Progeny
Hazrat Qais had two children, Alfakeh and Umme Harith. They were both born to Amama bint Mu‘az. The progeny and offspring of Hazrat Qais (ra) did not continue further. Hazrat Qais (ra) had three brothers, all of whom had the blessed opportunity of spending time in the company of the Holy Prophet (sa). However, they were unable to participate in the Battle of Badr. From among them, Hazrat Harith (ra) was martyred in the Battle of Yamama and Hazrat Abu Kilaab (ra) and Hazrat Jabir (ra) bin Abi Sa‘sa were martyred in the Battle of Mautah.
