God knows everything, even the innermost, i.e. the most latent endowments of the feelings and thoughts of each individual. The life-vein i.e. the jugular vein which is the big trunk vein, running on each side of the neck which brings the blood back from the head to the heart, which is considered so near to the life of an individual is cited here just to illustrate that God is nearer to the very existence of the individual than the very vein on which his life depends.
Declaration of Allah’s (swt) Perfection and Absolute Oneness Surah Ikhlas, 112:1-4 قُلْ هُوَ اللَّهُ أَحَدٌ Qul Hu-wal-laahu ’Ahad; Say: “He is the One God: اللَّهُ الصَّمَدُ . ’Al-laahus-Samad; God the Eternal, the Uncaused Cause of All Being. لَمْ يَلِدْ وَلَمْ يُولَدْ Lam yalid, wa lam yuulad; He begets not, and neither is He begotten; وَلَمْ يَكُن لَّهُ كُفُوًا أَحَدٌ Walam yakul-la-Huu kufuwan ’ahad.

God is He save whom there is no deity: the Sovereign Supreme, the Holy, the One with whom all salvation rests, the Giver of Faith, the One who determines what is true and false, the Almighty, the One who subdues wrong and restores right, the One to whom all greatness belongs!
