(a.) is the usual name for the conclusion resulting from the combination of the two premisses (muḳaddamāt) in the syllogism (ḳiyās). It corresponds to the Stoic ἐπιΦορά; this word in the works of Galen known to the Arabs is applied to the various discharges from the body but also means, as with the Stoics, the conclusion. Aristotle used the word συμπέρασμα: that which concludes or completes the syllogism.
In place of the usual natīd̲j̲a we also find ridf or radf (= deduction).
