Can one is religious without performing religious rituals or uttering the name of the God?

yes it does not matter that you perform rituals or not it is just a matter of believing in god from heart i also do not perform rituals or take part in it . that means i am not religious that is absolutely wrong.

yes i am religious i don't utter name of god and perform any religious rituals

God just wants us to be honest, help others unselfishly & have faith in HIM. Religious rituals are not essential.

Certainly, and it is the more easier way to serve His purpose.God never ask us to remember His name or worship Him. He simply requires to do good to ourselves an other alike. To have sympathy with all living beings and respect the nature and His commandments.

Let me ask 2 counter question to the questioner. Have you ever thought who created you? and what do you think is the purpose of your creator that he created you for?

Our Creator says: "I have not created Jinn & Human beings but to worship me". And he also taught us how to worship him.

Yes.

certainly you keep it in your mind

No.
