Islam critiqued finds grace; Allah the merciful?

In answer to the video "Allah is NOT Forgiving, Merciful or Loving"

Forgiveness is the key that opens the Garden of heaven and such forgiveness is only for those who reach the afterlife in a state of inner awe of God as well as a repentant heart 50:31-3,57:21. Since paradise is a place of purity and cleanliness; a person tarnished by the impurities of sins, even the minutest ones, cannot enter it only after forgiveness. It is granted at different stages after death, depending on the necessary cleansing process that will be needed for each individual.

While some will receive it immidiately and therefore will not be made to experience any difficulty after death and until their entry in Paradise, others will go through the "fitna", as will be detailed a little later. Almost all verses speaking of the reward in the Hereafter of the pious, the righteous, who do their utmost to avoid sinning, first mention that will receive God's forgiveness 3:133,5:9,34:4,35:7,36:11,64:9,67:12.

God's gracious forgiveness which is granted to the meritorious in the hereafter, also shows that He isnt like a miserly master who checks his servant on trivialities but instead He overlooks the errors of His obedient, sincere servant and rewards him exponentialy

35:29-30"Surely they who recite the Book of Allah and keep up prayer and spend out of what We have given them secretly and openly, hope for a gain which will not perish. That He may pay them back fully their rewards and give them more out of His grace: surely He is Forgiving, Multiplier of rewards".

This is Allah's grace that manifests itself in so many ways. It is by God's grace that one enters paradise in the first place because in reality none of our deeds are as perfect and faultless so as to grant us such rewards. These rewards are only the consequence of God's mercy and grace that He overlooks the servant's weaknesses and defects so long as he commits himself to piety and avoids the great sins, reforms himself and does not dwell in a state of transgression in which he stumbled into

4:17-18,53:32"surely your Lord is liberal in forgiving".

Allah is liberal in forgiving and accepts the faithfull's services despite their imperfections, and blesses him with rewards; otherwise if He resorts to minute accountability no one can dare claim to win Paradise only on the strength of his own deeds

44:51-7"Surely those who guard (against evil) are in a secure place,..and He will save them from the punishment of the hell, a grace from your Lord; this is the great achievement".

The Quran reiterates this principle many times 52:18,27 that the reward of the Hereafter is really a divine grace due to God's mercy that He overlooks the righteous believer's small misdeeds and imperfections. Otherwise, in reality and in accordance with blind justice these misdeeds actually require a certain degree of punishement. Yet He forgives the trespasses and only considers the best of a faithful servant's wordly deeds

39:35"So that Allah will do away with the worst of what they did and give them their reward for the best of what they do".
