Is one who pronounces the letter "Qaf" as a glottal stop (hamza) in a name like "Abdul Razzaq" (thus making it "Abdul Razza’") sinful due to their dialect, knowing that they do not intend thereby to attribute servitude to other than God or to debase the name?

He who speaks in a dialect that does not distinguish between شرعي (Shar'i) terms, such as the Beautiful Names of Allah, does not intend disrespect, offense, distortion, or atheism. Therefore, he is not judged sinful, nor is his utterance deemed forbidden. Nevertheless, it is preferable for him to endeavor to articulate the Beautiful Names of Allah and respected شرعي (Shar'i) terms eloquently. The substitution of letters is an old and known linguistic phenomenon, such as the substitution of the letter Qaf with a hamza, a phenomenon widespread in some contemporary colloquial dialects. This linguistic phenomenon does not necessitate sinfulness for the one who utters it, but he is requested to strive for eloquence when pronouncing شرعي (Shar'i) terms.
