If a person is interested in the boiling of water...
If a person is interested in the boiling of water, he should arrange the materialization of the appropriate conditions stipulated in the law of boiling, and if he wants water not to boil, he should ensure that water is not heated to the boiling point. Hence, a law advanced in the form of a conditional sentence has a constructive value in human life. From the above it also becomes clear that there is a philosophy behind the expression of laws in the form of conditional sentences.
Allah has based the system of this world on universal laws and firm norms. He draws man's attention to this firm and compact system of the world so that man may know where he stands in it. Allah tells man about the factors which make or mar his life so that he himself may be able to meet his due needs properly.
If the boiling process of water was to take place accidentally, was not subject to a definite law and did not require heat, man could not control this process, nor would it have been possible for him to boil or not to boil water as he wanted. Man acquired this skill when he came to know the definite norms and firm laws of the world. The laws of nature have been put forward to him in the form of conditional propositions, thus enabling him to see things in light, not in darkness.
In the light of the laws of nature he can determine his course of action in regard to the world. Exactly the same applies to the forms in which the Qur'an enunciates the laws of history. In many cases we find these laws put forward in the form of conditional statements. For this purpose the Qur'an mentions two interconnected social or historical phenomena and says whenever the first phenomenon appears, the second phenomenon is bound to appear.
It does not say when the first phenomenon appears or when it does not. Several of the Qur'anic verses mentioned by us earlier narrate the historical laws in the form of a conditional statement. In this connection the following verse may be recalled: Allah does not change the condition of a people unless they change what is in their hearts.
(Surah ar-Ra'd, 13:11) Here a law of history has been mentioned, and as we explained earlier and will further explain later, it has been put forward in the form of a conditional statement, for the verse says that there exists an inseparable link between the two different changes, namely a change in man's inner content and a change in his external position. Substantially this is a case of conditional statement.
