A more specific case occurs when the nominal subject itself is the pronoun of the bearer, as in جَاءَ زَيْدٌ وَهُوَ مُسْرِعٌ. The pronoun huwa serves as the subject of the circumstantial clause, while musriʿun is its predicate.
A strong grammatical argument favors explicit wāw here, since beginning with a freestanding pronoun can sound like a separate predication. Yet the universality of a strict obligation is disputed. The analysis must therefore distinguish the proposed reason for wāw from an unqualified claim about every textual example.
