How do I trust God’s existence when I don’t see Him?

Our faith in God’s (Allah) existence without seeing Him is the only belief that makes us Muslim. Shahada’ ( ) is a testimony which reads “I bear witness that there is no deity but God, and I bear witness that Muhammad is the messenger of God.” Someone who bears knowledge would look at the signs to prove His existence rather than finding His physical appearance.

“Say: ‘Praise be to God. He will show you His Signs and you will recognize them. Your Lord is not heedless of anything you do.’” (Qur’an, 27:93)

“This is a communication to be transmitted to mankind so that they can be warned by it and so that they will know that He is One God and so that people of intelligence will pay heed.” (Qur’an, 14:52)
In many other verses, God emphasizes that one of the most crucial purposes of the Qur’an’s revelation is to invite people to ponder.

In the Qur’an, God invites people to reject blindly accepting the beliefs and values society imposes on them and to ponder by pushing aside all the prejudices, taboos and constraints on their minds.

Man must think on how he came into being, what the purpose of his life is, why he will die and what awaits him after death. He must question how he, himself, and the whole universe came into existence and how they continue to exist. While doing this, he must relieve himself of all constraints and prejudices.

By thinking while isolating his conscience from all social, ideological and psychological obligations, the person should eventually perceive that the entire universe, including himself, is created by a superior power. Even when he examines his own body or any other thing in nature, he will see an impressive harmony, plan and wisdom at work within its design.

Concerning this point again, the Qur’an guides man. In the Qur’an, God guides us as to what we should reflect on and investigate. With the methods of reflection given in the Qur’an, he who has faith in God will better perceive God’s perfection, eternal wisdom, knowledge and power in His creation. When a believing person starts to think in the way shown in the Qur’an, he soon realizes that the whole universe is a sign of God’s power and art, and that, “nature is a work of art, not the artist itself”. Every work of art exhibits the exceptional skills of the one who has made it and conveys his messages.

In the Qur’an, people are summoned to contemplate numerous events and objects that clearly testify to the existence and uniqueness of God and His attributes. In the Qur’an, all these beings that bear witness are designated as “signs,” meaning “tested evidence, absolute knowledge and expression of truth.”
Therefore, the signs of God comprise all the beings in the universe in that they disclose and communicate the being and attributes of God. Those who can observe and remember will see that the entire universe is entirely composed of the signs of God.

Allah is keeping his meeting with Mutaqeens in Jannah(paradise) as a reward for their steadfast struggle to stay on the righteous path in this world. Our duty as a Muslim is to follow what He asked us to do in Quran and what Prophet Muhammad (PBUH) guided us to do which is also called Sunnah.
