Muslims around the world have a common belief that in this world we cannot see our LORD, but in Jannah we will be blessed and well be able to see Allah.
There are many evidences from Quran and Sunnah on which the belief is based on. In the Holy Quran it is mentioned:
Some faces that Day shall be Nadirah (shining and radiant). Looking at their Lord (Allah).” [al-Qiyaamah :22-23]
There are many ahadith in which Prophet (PBUH) told us that in Jannah people will be blessed by having a glance to their creator. This was mentioned in Muslim in these words “The veil will be removed and they will not be given anything more beloved to them than looking at their Lord, may He be glorified and exalted”
So we should believe in the words of our Lord and his beloved messenger about seeing the Lord.
