“And We have already created man and know what his soul whispers to him, and We are closer to him than [his] jugular vein” [Quran 50:16]
Verily, Allah is very near. He sees and knows every aspect of a human being, and hears every word he utters. He is knowledgeable of even one’s inner thoughts.
Allah says in Quran
“And if you speak aloud – then indeed, He knows the secret and what is [even] more hidden.” [Quran 20:7]
Nothing is hidden from Allah, nobody is closer to us then He since He even knows what we don’t speak and what we have in our hearts
“Have you not considered that Allah knows what is in the heavens and what is on the earth? There is in no private conversation three but that He is the fourth of them, nor are there five but that He is the sixth of them – and no less than that and no more except that He is with them [in knowledge] wherever they are. Then He will inform them of what they did, on the Day of Resurrection. Indeed Allah is, of all things, Knowing.” [Quran 58:7]
Allah is closer to us then jugular veins. If the veins or arteries are cut, they lose their soul and die. In short, Allah encompasses complete and full knowledge about everything of man, because He is ‘closer to him than his neck-vein.
The point is that how much do we try to get closer to Him?
On the authority of Abu Harayrah (may Allah be pleased with him), who said that the Prophet (PBUH) said: Allah the Almighty said: I am as My servant thinks I am (1). I am with him when he makes mention of Me. If he makes mention of Me to himself, I make mention of him to Myself; and if he makes mention of Me in an assembly, I make mention of him in an assemble better than it. And if he draws near to Me an arm’s length, I draw near to him a fathom’s length. And if he comes to Me walking, I go to him at speed.
(1) Another possible rendering of the Arabic is: “I am as My servant expects Me to be”. The meaning is that forgiveness and acceptance of repentance by the Almighty is subject to His servant truly believing that He is forgiving and merciful.
However, not to accompany such belief with right action would be to mock the Almighty.

In another Hadith Qudsi it is stated
On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (PBUH) said: Allah (mighty and sublime be He) said:
Whosoever shows enmity to someone devoted to Me, I shall be at war with him. My servant draws not near to Me with anything more loved by Me than the religious duties I have enjoined upon him, and My servant continues to draw near to Me with supererogatory works so that I shall love him.
When I love him I am his hearing with which he hears, his seeing with which he sees, his hand with which he strikes and his foot with which he walks. Were he to ask [something] of Me, I would surely give it to him, and were he to ask Me for refuge, I would surely grant him it.
I do not hesitate about anything as much as I hesitate about [seizing] the soul of My faithful servant: he hates death and I hate hurting him.
