Brief answer
According to the judgment of reason and the law of God Almighty, - neither in this world nor in the Hereafter - it cannot be seen with the eye of the head, but it can be seen with the eye of the heart. Hearts perceive and understand Him to the extent of their existential capacity, through inner intuition, after the inner purity and purification of the soul through the purification of the soul and the purity of the soul through the blessings of religious worship and austerities.
Detailed answer
If what is meant by seeing is seeing outwardly and with the eyes, then God cannot be seen, both according to the judgment of reason and according to the statement of the law.
However, according to the judgment of reason; the operation of seeing and seeing takes place through the encounter of an external object with the eye and the light vibrations of sending and reflecting light waves; that is, first: it must be an external object; second: the encounter and alignment of the external object with the eye; Therefore, our eyes do not see the objects behind the head, while God is neither a body nor has the characteristics and characteristics of a body (such as facing); therefore, He will never be seen with the eyes of the head.
However, according to the Sharia: The Quran and the narrations clearly consider it impossible to see God.
a) The Quran:
He said: “You will never see me”;[1] O Moses, you will never be able to see me.
“La tadrakah al-absara”;[2] The eyes do not see Him.
b) The narrations: “And He withheld Himself from the eye of the All-Seeing”;[3] meaning, God never appears before the eyes of the All-Seeing.
“Lama tarka al-a’yun”;[4] The eyes have not seen You.
“Lat takrah al-a’yun bi-mashhadah al-a’yun”;[5] The eyes will never see Him clearly.
But if what is meant by seeing is inner seeing and knowledge, knowledge and witnessing the names and attributes of God Almighty, then of course, it is inner seeing to the extent of the capacity, aptitude and ability of humans. As Ali (AS) said: “But the understanding of the hearts”;[6] hearts and minds understand Him.
And in another hadith, Imam Ali (AS) said to Dhul-Abb: And O you, the eyes do not see Him, but the hearts do see Him.[7]
