Hearing the speech in the proper manner, understanding its intended meaning, and then memorizing it and being committed to it.
Scholars stipulate "dabt" (precision) and proficiency in many issues related to Fiqh (Islamic jurisprudence), like giving testimony in the court, since "dabt" precludes falsification and lying, whether intended or unintended. A witness who remembers well and is attentive will give a sound testimony free from errors and the like.
"Dabt": adhering to something and not departing from it. Original meaning: to preserve something firmly. It can also mean strength and strictness. Opposite: "tafreet" (carelessness), "tadyee‘" (negligence), "‘ajz" (incompetence). Other meanings: care, seizure, restriction, specification.
To pay full attention to something so as to master it and retain it fully.
