The home of Wazirs and Maseeds has always been Afghanistan, I will give you an example, there is a village called Badar/momi karamay, it use to be inhabited by Wazirs, but Maseeds fought them and expelled them from the land, and pushed them more to the North and Wana/South. Maseed and Wazirs came to Waziristan from Afghanistan, the real inhabitants of Waziristan can be considered the urmur people/burki.
