Induction (istiqrāʾ) examines particular cases and arrives at a more general judgment. For example, repeated observations that samples of a type of metal expand when heated may motivate a general rule about that metal.
The samples are particular instances; the proposed rule is general. If not every relevant case has been examined, a counterexample may still be possible.
Thus moving from particulars to a generalization differs from a syllogism in which the conclusion follows from the stated structure of the premises.
