A ---Allah the Almighty says: 

{Except for those who bear witness to the truth knowingly} i.e. believe in the Oneness of Allah, {and they know}.

(Az-Zukhruf, 86) 

i.e. they know in their heart the facts about the Oneness of Allah and its meaning.

Prophet Muhammad (Peace be upon him) says:

 "He who died knowing (fully well) that there is no god but Allah entered Paradise ".

(Sahih Muslim)
