مَعَ غَايَةٍ مِنَ التَّنْقِيحِ وَالتَّهْذِيبِ
With the utmost clarification and refinement.
Tanqīḥ isolates the real issue by removing irrelevant branches, unsupported possibilities and distracting complications. Tahdhīb refines the expression and organization of the material so that it becomes precise and fit for serious study. Neither is simply a matter of making prose shorter or more technical.
Suppose the question concerns a divine attribute. Excluding unrelated historical stories helps isolate the issue; arranging the remaining definition, claim and evidence improves its presentation.
This is how a difficult argument can become accessible without losing its necessary depth.
