Salaam. I'm in a state where I'm a born Muslim, but thinks that I don't want to commit to Islam or a certain religion. What do you call this? And what should I do? I feel wrong, but somehow it is liberating to imagine if I were to bound by no religion. Does only believing the existence of God suffice?
I understand the desire to want to be part of a “larger” truth instead of restricting yourself to one religion. Unfortunately this does not work for the simple reason that God does not approve of it. As a Muslim, you have inherited the legacy of Islam and God accepts no religion other than Islam from you. The Quran says:
Whoever [among the Muslims] seeks other than Islam as a religion, it will not be accepted from him, and in the Hereafter he will be among the losers.
How will God guide a people who disbelieved after having believed, and had witnessed that the Messenger is true, and the clear proofs had come to them? God does not guide the unjust people.
Those—their penalty is that upon them falls the curse of God, and of the angels, and of all mankind.
Remaining in it eternally, without their punishment being eased from them, and without being reprieved.
The Quran, verses 3:85-88.
From God’s perspective Islam is a truth that no Muslim has a right to deny. Breaking away from Islam means breaking away from the truth, and this is a sin that God does not forgive.
There is no higher moral law in our universe to justify your leaving Islam for the sake of believing in God without religion. If you believe in God, you must be willing to seek Him out and seek out His revelations and sincerely ask Him for guidance. You cannot just say that you believe in God and expect this to suffice you. God has plans for you and makes demands on you. You either humbly submit to this or you arrogantly think that you are above God’s wishes.
