Unity of the ruling (ittihad al-hukm)

اتحاد الحكم

Literally ittihad is two things becoming one, and the ruling (hukm) is God's address concerning the acts of responsible persons, by demand, by choice or by stipulation. 1 The usulis treat unity of the ruling in two places: when a word appears unrestricted in one text and restricted in another, and when one ruling has several causes. 1 The majority allow one ruling to have two or more causes, and they hold that this occurs: touching, contact and urination each prevent prayer. Ibn Furak and al-Razi allowed it only for causes stated in the text and not for derived ones; the author of Jam' al-Jawami' held that it is rationally impossible. 1

Summary

Ittihad is two things becoming one; the ruling (hukm) is God's address concerning the acts of responsible persons, by demand, by choice or by stipulation. 1 The usulis treat unity of the ruling in two places: when a word is unrestricted in one text and restricted in another, and when one ruling has several causes. 1

Several causes for one ruling

The majority allow one ruling to have two or more causes, since legal causes are signs and nothing prevents several signs from pointing at one thing; they hold that this occurs, as touching, bodily contact and urination each prevent prayer. 1 Ibn Furak and al-Razi allowed it for causes stated in the text but not for derived ones; the author of Jam' al-Jawami' held that it is rationally impossible. 1

Where it is discussed

The fuller treatment is in the usul appendix; unity of the cause (ittihad al-sabab) is treated under its own heading. 1

Biting and the liability for injury it causes (add)

In the lexicon, add is gripping a thing with the teeth and holding it. If a person bites another without right and a wound results, the biter must pay the damages for the wound, assessed as a just award by experts. If one man bites another's hand and the bitten man pulls it free so that the biter's front teeth fall out, most jurists hold that there is no liability, relying on a prophetic judgement in such a case; the Shafi'is limit this to a bitten man who chose the easiest means of release, and the preferred Maliki view requires compensation.
