The transformation, evolution and development of the means of living and progress in the various elements of civilization have no kind of incompatibility with the eternity of the commands of Islam, because the incompatibility of a law with this kind of progress is
because the law depends on fundamental means and special factors. For example, if one makes a law: only the hand must be used when writing, only a donkey must be used for travel, etc. this kind of law cannot come into action when science and civilization advance but if it is not in contradiction with fundamental means, and at the time of making the law these were only used as examples, they will not clash with the occurrence of now means and the advance of civilization.
Islamic laws are of this latter category that is to say they do not look especially at the means of one period in history. For example, they say: one must be unconquerable with regard to foreign powers so as to defend one’s vital and human rights. This law, although it was declared in the time of the sword, never depends on the instruments of that time, i.e. Islam never says:
The Islamic jihad must only be with swords. Thus it is practicable today. Similarly with business transactions, trade, word, etc. So, however much civilization and its means and elements expand, it will never leave the domain of inclusion in the laws of Islam, and this is one of the secrets of eternity of Islam.
Does Islam Dispense with contemporary Idealogies and systems of Thought?
There is no doubt that man has progressed far in the way of knowledge, but scientists themselves confess that what they know in the world of creation is not comparable with what they do not know and basically, since their vision is limited, they cannot find out all the secrets of the world. Moreover, each leap forward that man makes is not immune from error.
Therefore, in the area of human aspirations, not everything that comes forward, in every field, can be one hundred percent imbued with certainty, because it is possible that environmental factors and other unforeseen thing have an effect on man”s thinking and outlook and take him far from reality. But the fundamental project of Islam, since it grows from the root of revelation, has nothing to do with the possibility of mistake, and can give trustworthy guidance at all times of course, with the condition that these pure laws are not inserted within the framework of other deviated systems, whereupon they the become completely incapable of deriving advantage.
