Why does Allah not need someone to introduce you to Him or remind Him of you?

Allah knows you before you speak.

He knows:

what is in your heart,

what you are thinking,

and what you need even before you ask for it.

The idea that someone introduces you to Allah or draws His attention to you

is based on likening God to humans, and this is something Islam completely rejects.

The direct relationship

Supplication in Islam does not require:

a clergyman,

or an intermediary,

or a specific language.

It is enough for the supplication to arise in your heart.

The danger of relying on an intermediary

When a person becomes accustomed to directing his needs to other than Allah,

the heart gradually shifts from relying on the Creator

to relying on a created being.

And this strips the relationship with Allah of its true meaning.

Summary of the idea

The God who knows everything does not need someone to introduce you to Him,

and the human being does not need someone to represent him before Allah.

The relationship in Islam is direct, pure, and simple.
