dontconvert2islam still in a fog; division of people in the hereafter?

In answer to the video "The Chances of Islamic Salvation?"

People will be divided into 3 groups; the foremost in faith who will have precedence over the others and will be drawn close to God (more from old times than later times 56:13-14), the righteous (more from the old as well as late times 56:40) and the wrongdoers 56:7-11. This shows that the communities and groups that have been formed in the world on the basis of race, country, language, tribe and clan, and economic and political interests, will break, and the people will be re-grouped on the basis of true belief, morality and character.

Each group will have to answer to a different level of reckoning, going from fast and easy to difficult and lengthy. 

The first group wont be reproached for their minor sins and shortcomings, will be forgiven and redeemed through their good deeds. Once made to enter paradise, the reward awaiting them will be made to match not any deed, but the best of them at least. 

Then by God's grace their reward will be made to surpass what is proportionaly due to them 6:160,16:96-7,29:7,39:35,46:16,84:8. It is clear that in Islam, the righteous' good deeds in themselves are not what grant him salvation in the hereafter. They serve as a measure of a person's faith in God. It is then God's grace that translates exponentially that level of faith, whose indicator are the deeds, into reward in the hereafter.

On the other hand, others will be requited for the worst of their deeds, all the bad that they accumulated, including the smallest sins. 

These small sins wont be forgiven immidiately as with the previous group 13:21,46:16,74:38-9 hence their lengthy and difficult reckoning 13:18,41:27,74:9-10. This minute, but just requital will fall upon them on a day like a crushing weight 75:25. They will be reprimended for every one of their misdeeds, great or small. 

Depending on each case, that requital will occur starting from their earthly death, in the intermediary period that precedes the resurrection, meaning the barzakh. It will go on during the Resurrection and Hell if necessary, before they are finally granted forgiveness and potential entry in Heaven. Some will certainly have to go through the last stage, dwelling in Hell, before they are purged from their sins but others will be cleansed through prior processes. As God says elsewhere even in reference to the followers of the devil himself

7:18"Whoever of them follows you, I will surely fill Hell with some/min of you all".

This is because each person's circumstances that lead him to follow a certain path are different. Only God is capable of integrating such intricacies in a perfect individual judgement. The vast majority of mankind will have to undergo one of, or a combination of these stages of requital -the grave, the resurrection, and hell- while a tiny fraction will enter heaven without rendering any account.  

This is the idea behind the prophet's reported statement that from among Adam's progeny 99% of mankind will be singled out for hell. It doesnt however say that these 99% will all be made to enter it, just that they will certainly deserve it. As said above, some will have to go through it while others will sufficiently be retributed and cleansed through prior processes.

Those who are destined for Heaven, without undergoing any cleansing process, will not be brought anywhere near Hell. They will be so far removed from it, they will not hear the sound of its roar on the Day of Resurrection

92:17,26:90,21:98-103"Surely you and what you worship besides Allah are the firewood of hell; to it you shall come. Had these been gods, they would not have come to it and all shall abide therein. For them therein shall be groaning and therein they shall not hear. Surely (as for) those for whom the good has already gone forth from Us, they shall be kept far off from it, They will not hear its faintest sound, and they shall abide in that which their souls long for. The great fearful event shall not grieve them, and the angels shall meet them: This is your day which you were promised".

The supreme awesomness of this Day will not grieve the righteous, who shall in addition be protected from its upheaval and afflictions 2:277,21:103,88:8,76:7-11. Through a subtle linguistic device, the Quran explains this idea of the righteous believers on that day being far removed from the terror "no fear upon them, and nor shall they grieve". The first part of the verse pictures a caring entity looking over with full understanding of the situation without any fear while watching the scene. A practical example would be of a child who might be fearlessly playing with a snake, not knowing the impending danger but the mature person watching over, understanding the situation, would be full of fear and worry. 

On the last day however, because the successful will be fully justified in lacking fear and feeling secure despite the surrounding terrifying events, then the caring entity watching over wont have any fear upon them. The same phrase is used in 7:49 for the dwellers of heaven, they are in such secure conditions that none will have any reason to fear for them.

As Solomon reportedly says concerning the righteous in the life to come

Prov1:33"But he who hearkens to me shall dwell confidently and shall be tranquil from the fear of harm".

The righteous will thus proudly exclaim to all to come read from his book of deeds held in evidence in his right hand, the Iliyin 69:19,83:18,84:7. He shall be secured from harm 41:40, relieved with sustenance from heaven before entering it. The traditions speak of a Pool the water of which is from the Garden, and from which the believers shall drink before entering the Garden. Those that will be prevented from this favor on account of their sins, will long for a portion of that sustenance 7:50,19:86. They will wish for a share of the light beaming upon the righteous with such force that it will emanate from them 57:13-15. The absence of light upon the wicked on the day of judgement is alluded to in the Hebrew Bible, including in Job38:14-15.

The futur dwellers of heaven will be greeted with the best greetings by the angels and God Himself, honored and given the good news of Heaven from the moment of their earthly death 16:32,41:30 until their resurrection and entry in Heaven 7:46,13:23-4,14:23,15:45-8,21:103,36:58,39:73,56:26. 

This doesnt sound in anyway as if all people will be made to suffer after death as suggested by this youtuber. 

Once in heaven, no lewd, empty talk will be heard, only peaceful and wise speech 19:62,56:25,88:11. They will keep greeting one another and praying for eachother's peace within heaven 10:10. On the other hand the hell dwellers, from the instant of their death where they will be violently seized by the angels and told they had been following the evil course 16:28-9,7:37,8:50,47:27 will endure a lengthy and difficult trial until they enter hell where they shall incessantly quarrel among oneanother, receive each new comer with open hostility for having influenced one another in sin 38:55-60, cursing, denying and blaming one another.
