Abdul Rahman Ghaleb was born in the 1980s in Bajaur Agency, part of the Federally Administered Tribal Areas of Pakistan.

In late August 2016, Ghaleb was the emir for Nangarhar Province and reported to be a deputy of then-ISIS–K Wali Abdul Haseeb Logari.

Abdul Rahman Ghaleb was killed in a US strike on ISIS–K's headquarters in the Watapur District of Kunar Province on 11 July 2017 along with other key members of the group.

Pentagon spokeswoman Dana White remarked that Ghaleb's killing "will significantly disrupt the terror group's plans to expand its presence.

"[9] Ghaleb's successor, Abu Saad Erhabi, was chosen quickly after and would serve until his killing in August 2018 in a combined raid by forces of the United States military and Afghan National Directorate of Security (NDS).
