لااَّ تُدْرِكُهُ الااَبْصَارُ
...
No vision can grasp Him,
in this life.
The vision will be able to look at Allah in the Hereafter, as affirmed and attested to by the numerous Hadiths from the Prophet through authentic chains of narration in the collections of the Sahihs, Musnad and Sunan collections.
As for this life, Masruq narrated that Aishah said,
"Whoever claims that Muhammad has seen his Lord, will have uttered a lie against Allah, for Allah the Most Honored, says,
لااَّ تُدْرِكُهُ الااَبْصَارُ وَهُوَ يُدْرِكُ الااَبْصَارَ
(No vision can grasp Him, but His grasp is over all vision.)"
In the Sahih (Muslim) it is recorded that Abu Musa Al-Ashari narrated from the Prophet,
إِنَّ اللهَ لاَ يَنَامُ وَلاَ يَنْبَغِي لَهُ أَنْ يَنَامَ يَخْفِضُ الْقِسْطَ وَيَرْفَعُهُ يُرْفَعُ إِلَيْهِ عَمَلُ النَّهَارِ قَبْلَ اللَّيْلِ وَعَمَلُ اللَّيْلِ قَبْلَ النَّهَارِ حِجَابُهُ النُّورُ أَوِ النَّارُ لَوْ كَشَفَهُ لاََحْرَقَتْ سَبُحَاتُ وَجْهِهِ مَا انْتَهَى إِلَيْهِ بَصَرُهُ مِنْ خَلْقِه
Verily, Allah does not sleep and it does not befit His majesty that He should sleep. He lowers the scale (of everything) and raises it. The deeds of the day are ascended to Him before the night, and the deeds of the night before the day. His Veil is the Light -- or Fire -- and if He removes it (the veil), the Light of His Face will burn every created thing that His sight reaches.
In the previous (revealed) Books there is this statement,
"When Musa requested to see Him, Allah said to Musa:
`O Musa! Verily, no living thing sees Me, but it dies and no dried things sees me, but it rolls up."'
Allah said,
فَلَمَّا تَجَلَّى رَبُّهُ لِلْجَبَلِ جَعَلَهُ دَكًّا وَخَرَّ موسَى صَعِقًا فَلَمَّأ أَفَاقَ قَالَ سُبْحَـنَكَ تُبْتُ إِلَيْكَ وَأَنَاْ أَوَّلُ الْمُوْمِنِينَ
So when his Lord appeared to the mountain, He made it collapse to dust, and Musa fell down unconscious. Then when he recovered his senses he said: "Glory be to You, I turn to You in repentance and I am the first of the believers." (7:143)
These Ayat, Hadiths and statements do not negate the fact that Allah will be seen on the Day of Resurrection by His believing servants, in the manner that He decides, all the while preserving His might and grace as they are.
The Mother of the Faithful, Aishah, used to affirm that;
Allah will be seen in the Hereafter, but denied that it could occur in this life, mentioning this Ayah as evidence,
لااَّ تُدْرِكُهُ الااَبْصَارُ وَهُوَ يُدْرِكُ الااَبْصَارَ
(No vision can grasp Him, but His grasp is over all vision). Her denial was a denial of the ability to encompass Him, meaning to perfectly see His grace and magnificence as He is, for that is not possible for any human, angel or anything created.
Allah's statement,
...
وَهُوَ يُدْرِكُ الاَبْصَارَ
...
but His grasp is over all vision.
means, He encompasses all vision and He has full knowledge of them, for He created them all.
In another Ayah, Allah said;
أَلاَ يَعْلَمُ مَنْ خَلَقَ وَهُوَ اللَّطِيفُ الْخَبِيرُ
Should not He Who has created know! And He is the Most Subtle, Well Acquainted (with all things). (67:14)
It is also possible that `all vision' refers to those who have the vision.
As-Suddi said that Allah's statement,
لااَّ تُدْرِكُهُ الااَبْصَارُ وَهُوَ يُدْرِكُ الااَبْصَارَ
(No vision can grasp Him, but His grasp is over all vision.) means,
"Nothing sees Him (in this life), but He sees all creation."
...
وَهُوَ اللَّطِيفُ الْخَبِيرُ
He is the Most Subtle, Well-Acquainted (with all things).
Abu Al-Aliyah said about Allah's statement that it means,
"He is the Most Subtle, bringing forth all things, Well-Acquainted with their position and place."
Allah knows best.
In another Ayah, Allah mentions Luqman's advice to his son,
يبُنَىَّ إِنَّهَأ إِن تَكُ مِثْقَالَ حَبَّةٍ مِّنْ خَرْدَلٍ فَتَكُنْ فِى صَخْرَةٍ أَوْ فِى السَّمَـوَتِ أَوْ فِى الاٌّرْضِ يَأْتِ بِهَا اللَّهُ إِنَّ اللَّهَ لَطِيفٌ خَبِيرٌ
O my son! If it be (anything) equal to the weight of grain of mustard seed, and though it be in a rock, or in the heavens or in the earth, Allah will bring it forth. Verily, Allah is Most Subtle, Well Acquainted. (31:16)
