I found this to be the best explanation to the existence of god, as its the darkest and hardest question of all time:
Imagination can not reach Him, so as to assign Him quantity.
Understanding can not think of Him, so as to give Him shape.
Senses do not perceive Him, so as to feel Him.
Hands can not touch Him, so as to rub against Him.
He does not change into any condition.
He does not pass from one state to another.
Night and days do not turn Him old.
light and darkness do not alter Him.
It can not be said that he has a limit or extremity, or end or termination; nor do things control Him so as to raise Him or lower Him, nor does anything carry Him so as to bend Him or keep Him erect.
He is not inside things nor outside them.
He conveys news, but not with the tongue or voice.
He listens, but not with holes of the ears or the organs of hearing.
He says, but does not utter words.
He remembers, but does not memorise.
He determines, but not by exercising His mind.
He loves and approves without any sentimentality (of heart).
He hates and feels angry without any painstaking.
When He intends to create someone he says “Be” and thee he is, but not through a voice that strikes (the ears) is that call heard.
His speech is an act of His creation.
The foremost in religion is the acknowledgement of Him, the perfection of acknowledging Him is to testify, the perfection of testifying Him is to believe in His Oneness, the perfection of believing in His Oneness is to regard Him pure, and the perfection of His purity is to deny Him attributes, because every attribute is a proof that it is different from that to which it is attributed, and everything to which is something is attributed is different from the attribute.
Thus whoever attaches attributes to God recognizes His like, and who recognizes His like regards Him two; and who regards Him two recognizes parts for Him; and who recognizes parts for Him mistook Him; and who mistook Him pointed at Him; and who pointed at Him admitted limitation for Him; and who admitted limitations for Him numbered Him.
Whoever said ‘in what is he?’ held that He is contained; and whoever said ‘on what is He held?’ He is not on something else.
He is a being but not through the phenomenon of coming into being.
He exists but not from non existence.
He is with everything but not in physical nearness.
He is different from everything but not in physical separation.
He acts but without connotation of movements and instruments.
He sees even when there is none to be looked at from among His creation.
He is the only One, such that there is non with whom he may keep company or whom He may miss in his absence.
