One must believe in the believers seeing Allah, ta^ala, with their eyes in the Hereafter. They will see Allah, with their eyes, while they are in Paradise, without Him having a form or being in a place or a direction, i.e., without Him resembling any of the creation. Allah ta^ala said in Surat al-Qiyamah verse #22-23:
﴿وجوه يومئذ ناضرة. إلى ربها ناظرة﴾ سورة القيامة
The verse means: [Some faces, that Day, will be radiant, looking at their Lord].
The Prophet, salla-l-lahu ^alayhi wa sallam, said:
“إنكم سترون ربكم يوم القيامة كما ترون القمر ليلة البدر لا تُضامون في رؤيته”، رواه مسلم
This means: “You will see your Lord on the Day of Judgment without any doubt, as you do not have doubt in seeing the moon on the night when it is full,” narrated by Imam Muslim.
The Prophet, salla-l-lahu ^alayhi wa sallam, did not liken Allah to the moon. Rather, our seeing of Allah will be of total certainty and no doubt, same as one having no doubt when seeing the moon at night when it is full. This was explicitly stated upon by Imam Abu Hanifah, radiya-l-lahu ^anhu, who said in ‘al-Fiqh al-Akbar’: “Allah ta^ala is seen in the Hereafter. The believers will see Him while they are in Paradise. [They will see Him] without any likeness, form, or quantity and there will not be any distance between Him and His creations.”
