教育的过程依赖于以下两条基本原则:(甲)顾及学生的理智水平;(乙)以能引导其思维朝正确方向前进的材料,培养他们的理智、精神和体能。《古兰经》分段降示,已经周密地顾及了这两项重要原则。

The process of education depends on the following two basic principles: (a) taking into account the mental level of the students, and (b) developing their mental, spiritual and physical abilities with material which guides their thought processes in the correct direction. Both of these important principles have been carefully taken into consideration by the revelation of the Qur’aan in segments.

立法的循序渐进，考虑到了穆斯林群体在其各个发展阶段的水平。在最需要的时候降示纠正与解答，使其理智、精神与身体的能力得到训练、发展，并被引向正确的方向。

Gradation of legislation took into account the level of the Muslim community during its various stages of development. The revelation of corrections and answers at the time when they were most needed trained, developed and guided the mental, spiritual and physical faculties in the right direction.

这里自然会产生一个问题：为什么早先的启示经典是整体降下的？答案在于早先经典的作用以及先知使命的历史。早先的经典只在人类历史的特定时期降下，并且是针对特定的民族或部落的。

The question which naturally arises here is why the earlier books of revelation were revealed as a whole. The answer to this question lies in the role of the earlier books and the history of prophethood. The earlier books were sent for short periods in human history and were directed to specific nations or tribes.

它们所包含的原则并不受时间或情境的限制，可以一次性降示，无论是在使命之初还是在使命进行的任何阶段。还应当指出，此前的经典本身并不是神迹，而对于最后的先知（ﷺ）而言，启示本身就是赐予他的最大神迹，因为正如前文所提到的，启示的分段降示与风格的一致性相结合，本身就是其神圣来源的证明。此外，前面的众先知，其前后都有其他先知，因此每位先知及其经典都只代表整体启示的一个部分。由此，立法的循序渐进是从一位先知到另一位先知逐步完成的。先知穆罕默德（ﷺ）是最后的先知，他的启示经典包含了此前所有经典的根本信息。因此，他的追随者必须得到妥善的准备，以便将最终的讯息传递给世界。如此一来，立法的循序渐进就必须在讯息本身之内完成。

They contained principles which were not time or situation oriented and could be revealed all at once, at the beginning of a mission or at any point during it. It should also be noted that the earlier books were not in themselves miracles, whereas in the case of the Last Prophet (ﷺ), it was the major miracle given to him, for, as was mentioned earlier, the segmentation of the revelation combined with the consistency of style was a proof of its divine origin. Also, the earlier prophets were both preceded and followed by other prophets, so each prophet and his book represented a segment of the overall revelation. Thus, the gradation in legislation took place from prophet to prophet. Prophet Muhammad (ﷺ) was the last of the prophets and his book of revelation contained the essential messages of all previous books. Thus, his followers had to be properly prepared to carry the final message to the world. As such, the gradation in legislation had to take place within the message itself.
