Waṣl ordinarily depends on a meaningful relation between two independent clauses. It may connect clauses equally declarative or equally non-declarative in form and function; it may also connect clauses with differing forms but a shared directive function. The Qurʾānic covenant illustrates the importance of the distinction.
The jāmiʿ is sought in the two predications, not merely in a generic common class. Context must supply a substantive connection. A subsequent analysis can then develop the rational, estimative, and imaginative kinds of association.
