Belief in the existence of Allah

Believing in Allah’s existence is made up of four evidences: Nature, Intellect, Experience, Religion

The Innate; the Natural
An innate behavior is such that it is not learned and not changed. It can be repressed but it is something that is genetically present.
Some things which are innate:
Thirst
Coughing
Yawning
Belief in God
One among many studies as evidence for the innate belief in God is this Oxford university study by Dr. Justin Barrot on the innate behavior of humans to believe in God before they learn how to disbelieve.

Intellect
Intellect used in context with the natural world and its systems paint a picture that points towards a creator that is knowledgeable and wise, because we are able to use things to our benefit, and sustenance. We are able to reason that things are designed in certain ways to have certain properties and certain effects and uses

Water
Water produces all types of plants, and makes up some portion of all living things. Water evaporates into the sky, gathers into clouds weighing millions of pounds that look soft and light, then the water falls in droplets soaking evenly into the ground producing food and materials, etc.

Ants
An ant has the brain the size of a few grains of sand and their social behaviors are smarter than many humans. They have systems of communication, they have guards, they have prisons, graveyards, trash dumps, they have Queens, armies, tactics for fighting, dealing with disaster, gardens, food storages, ventilation systems, etc.

Reasoning
Our intellect allows us to reason that these innate complex systems could not develop through a trial and error process without guidance, just as A.I. can not learn without its creators (the programmer) instruction an ants innate capacity to create something such as a graveyard needs

Experience
Experience is made of two things (that i can think of atm) our will and our emotion

Will
Our ability to think and do good things bad things or no things..

Emotion
Emotions are an innate tool to navigate experience, a way to sort what is good and what is evil and categorize these experiences accordingly

Religion
Religion is the way which Allah commanded His servants to behave

Believing in Allah’s Lordship by singling Allah in His actions
He is the creator, owner of everything, and handler of the affairs of all things. Allah is the only one who creates the only one that destroys, the only one who is eternal and self sustaining. For example:
Medicine
Medicine does not heal you without the action of Allah. Medicine is the means by which Allah heals.
Food
Food does not sustain you without the action of Allah. Food is the means by which Allah sustains you.

Consciousness
You breathe automatically, your heart beats automatically, your organs work automatically. These actions do not happen without the action of Allah. Your breath is the means by which oxygen is provided to your blood, your heart is the means by which that blood provides oxygen to your organs, your organs are the means by which your body lives.
Your body does not control your body. Your soul is the means by which your body is controlled, by you, to interact with the physical world and your soul is the means by which Allah allows you to interact. And Allah did not create mankind except to worship Him. And if that is the case, why are we able to disobey in the first place? What is free will and why do we have it? How do we know we have it? To what extent do we have it? This leads to the first point and our ability to use reason and intellect.

Singling Allah in the actions of worship that we do
Anything that Allah is pleased with and loves for his servants, is worship
Worship requires two things:

sincerity
You can not associate worship with anyone else; worship has to be sincerely only for Allah alone.
Accordance with the law
Innovation of Allah’s command is not accepted. Your worship must be in accordance with the Quran and sunnah.

Absolute reliance on Allah
If you find yourself in any situation, good or bad, you rely on Allah. Relying on other than Allah is shirk.

Minor shirk
Amulets
If you hang an amulet for protection, it is not absolute reliance on Allah for protection. This is minor shirk
Oaths
If you make an oath on the name of your mother “I put it on my mother” This is minor shirk. You do not believe your mother is Allah but you are relying on her to prove your honesty.

Major shirk
Associating partners with Allah
Praying to the prophets
Worshiping other than Allah alone
Seeking help from the dead or prophets other than Allah
Absolute submission to Allah
If Allah determines something, the attributes of the believers is to say “We hear and we obey”
You are submitting with love, not with fear. Allah says “If you love Allah then follow the prophet.”
Worship Allah with everything Allah is pleased with
Absolute obedience to Allah
Believing in the 99 attributes of Allah

Principles of the names and attributes of Allah
We can understand the meaning of something, and not understand how it is in reality.
We affirm to Allah what He affirmed to himself without negation, and without deviation, or saying Allah's attributes are 100% the same as the attributes of his creation.
Humans are hearing and seeing, but not in the same way of perfection that Allah is hearing and seeing
Only Allah knows how His attributes operate.
Allah descends in the last third of the night. How Allah descends we do not know, we accept that it happens. We understand the meaning of descend, we do not know how Allah descends.
All of Allah’s attributes are attributes of perfection
Meaning any attribute you hear from the Quran or Sunnah, regardless of what your mind thinks, is an attribute of perfection
