He who has the ability, with force, to make people do whatever He wants.
“ He is Allah, than whom there is no other God, the Sovereign Lord, The Holy One, Peace, the Keeper of Faith, the Guardian, the Majestic, THE COMPELLER, the Superb. Glorified be Allah from all that they ascribe as partner (unto Him).”
(59:23)” The Holy Quran
From the root j-b-r with the classical Arabic connotations: to restore something to sound, right or good state to bring back to normal, reform to benefit.
