Migration to Medina
When Hazrat Abu Kabsha migrated to Medina, he stayed with Hazrat Kulthum bin Al-Hadam. According to another narration, he stayed with Hazrat Sa‘d bin Khaithma. Hazrat Abu Kabsha passed away on the first night after Hazrat ‘Umar (ra) was elected as Khalifa. This was on the twenty-second Jamadi-uth-Thani [sixth month of the lunar calendar] in the thirteenth year of Hijra.
