Who was the Companion buried by the angels?

Al-Tabarani mentioned in "Al-Mu'jam Al-Kabeer" and Abd Al-Razzaq in "Al-Musannaf" that when 'Amir ibn Fuhayrah was buried after the Battle of Bi'r Ma'unah, his body could not be found, and they believed that the angels buried him. This 'Amir used to follow the footsteps of the Prophet, peace and blessings be upon him, and Abu Bakr, may Allah be pleased with him, with his sheep during the Hijrah to erase them.
