Al Qiyaas upon Al Hikmah: The difference between the ‘Illah and the Hikmah
The ‘Illah is the Baa’ith (reason or motive) for the legislation and it is taken from the text (An-Nass). There are however texts which appear to contain the meaning of reasoning according to the tools of reasoning utilised or in accordance to the composition of the sentence. Despite that there are other Qaraa’in (indicators or connotations), whether they are found within the text or not, which negate the meaning of reasoning whilst establishing another meaning which represents the Ghaayah (aim) of the legislator that is being targeted through the legislation.
This aim (Ghaayah) or result (Nateejah) that explains what has been intended from the Hukm by the Shaari’ (legislator) has been provided with the terminological naming of ‘Al-Hikmah’ (the wisdom) and it is not an ‘Illah because it is not the reason for the legislation.
Examples of these texts that include this ‘Hikmah’ include:
His Qawl Ta’Aalaa:
And We have not sent you except as a Rahmah (mercy) for all of that exists (mankind) (Al-Anbiyaa’ 107).
Rahmah (mercy) represents a description for the Sharee’ah in terms of the result of its application or implementation whilst it does not represent an ‘Illah for its legislation. That is because its Seeghah (form) does not indicate At-Ta’leel (reasoning). Consequently, the aspect of reasoning is negated and the Hikmah of the legislation of the Sharee’ah is Rahmah (mercy).
