Kitab At-Tawheed written by Sheikh-ul-Islam Muhammad bin Abdul-Wahhab – A renowned Reviver and a great Reformer
Allah the Almighty said:
“And I (Allah) created not the Jinns and men except they should worship Me (Alone).” (51:56)
And He stated:
“And verily, We have sent among every Ummah (community, nation) a Messenger (proclaiming): ‘Worship Allah (Alone), and avoid (or keep away from) Taghut (all false deities etc. i.e. do not worship Taghut besides Allah).’ ” (16:36)
