The the probabilistic forecasting method of the error between the sample mean and expectation value of the random variable utilizing the central limit theory was researched, then the mathematical formula for the relation between sampling size and variance coefficient of loss of load probability was analyzed. Furthermore, the formulas for the relation between confidence intervals of variance coefficient and sampling size are deduced.

For in the first place, it would mean that each evil act will be punished and each good act rewarded separately; secondly, it also means that no believer, however righteous and virtuous, will remain safe from being punished for a most ordinary error, and no disbeliever, however wicked and iniquitous, will be left unrewarded for a most ordinary good act, Both these meanings are opposed not only to the explanations given in the Qur'an and the Hadith, but also to reason.

如此做，从人的理智也是不能接受的。试想，主人在评判一个仆人时，不会原谅仆人的一丁点错误，尽管仆人是忠诚的、本分的；同理，就算仆人背信弃义，心怀不忠，主人还会因为仆人偶尔的服从去奖赏他——这是多么奇怪啊。而实际情况是应该如古兰经和圣训所描述的，其中为各种人制定了奖惩细则，分别针对信士、伪信士，非信士，正义的信士，犯错误的信士，罪恶的信士，普通非信士，罪恶累累的非信士，这些奖惩遍及人类的整个生活，从今世到后世。——这段改成这样了，能不能用你看着办吧，原文说话太绕了！！
