In ta‘liq, assertive expressions such as “qāla” differ from tentative expressions such as “ruwiya” or “yudhkar.” An assertive presentation carries stronger attribution by the compiler; it does not automatically prove that every omitted intermediary forms a sound, continuous chain.
Some narrations in Ṣaḥīḥ al-Bukhārī are presented in mu‘allaq form. Some have connected routes elsewhere; others require separate isnad investigation. “Mentioned in Bukhārī” is not identical to “transmitted there with a complete connected chain meeting its ordinary conditions.”
Principle: the formal interruption of one presentation and the reliability established through a separate complete route are distinct inquiries. Neither blanket acceptance nor blanket rejection of every mu‘allaq presentation is justified.
