In this world, the Straight Path comprises three levels: Islam, Iman and Ihsan. Whoever remains on the level of Islam until he dies will be saved from eternity in the Fire and he must enter Paradise, even if, before this, he is punished in the Fire. Whoever remains on the level of Iman until he dies will be prevented from entering the Fire altogether for the light of faith extinguishes the blaze of the Fire. Whoever remains on the level of Ihsan until he dies will reach Allah, “For those who do good is the best (reward) and an addition.” (Surah Yunus 10:26) The authentic hadith mentions, “When the People of Paradise enter Paradise a caller will announce, ‘People of Paradise, Allah has given you a praise which He wishes to fulfill.’ They will say, ‘What is that? Has He not made our faces white? Has He not made our scales heavy? Has He not granted us entry in Paradise and saved us from the Fire?’ So He will remove the veil and they will look on at Him and by Allah, He will not have granted them anything more beloved to them than this, and there will be nothing that gives more pleasure to their eyes than this! This is the addition.” then he recited the above verse. (Muslim)
All the inhabitants of Paradise will have a share of this vision but they will differ as to their closeness when seeing Him and in the number of times they see Him. All of the People of Paradise will see Him on the Day of Increase which is the Day of Jumuah (Tabarani) and the elite among them will look at the face of Allah twice a day, once in the morning and once in the evening.
“That Day will faces be resplendent, looking toward their Lord.” (al-Qiyamah 75: 22-23) It is because of this that the Messenger of Allah, peace and blessing of Allah be upon him, said in the authentic hadith reported on the authority of Jarir ibn Abdullah al-Bajali, “You will see your Lord on the Day of Judgement like you see the moon on a night when it is full, you will have no difficulty in seeing Him.” He then said, “So if you are able not to be overwhelmed to the point of missing a prayer before the rising of the sun and before its setting, then do so.” Then he recited, “And glorify your Lord – all the while praising Him – before the rising of the sun and before its setting.” (Surah Qaf 50:39) (Bukhari and Muslim)
